1.43 g of Boc-Ile-PAM resin (0.70 mmol/g, 1 mmol) was swollenin DMF for 1 hour, after which the terminal Boc group was removedwith 2 1 min treatment with neat TFA. The resin wasflow-washed with DMF for 30 s, and neutralized with 2 1 mintreatments with 10% DIEA in DMF (v/v). The neutralized resinwas then flow washed for 30 s with DMF, then 30 s with DCM.10 equiv of DCC (2.063 g, 10 mmol) were dissolved in 5 mL ofDCM and 20 equiv of 3-iodopropionic acid (4.0 g, 20 mmol) weredissolved in 6 mL of DCM. Both solutions were cooled to 0 Cfor 5 min before being combined and allowed to react at 0 C for30 min. The resulting solution containing 3-iodopropionic anhydridewas gravity filtered to remove the dicyclohexylurea precipitate.The residue was then washed with 2 mL of DCM, filtered, andpooled with the 3-iodopropionic anhydride filtrate. The pooled filtrateswere then added to the deprotected neutralized Ile-PAM resinand allowed to couple for 45 min. The resin was drained andwashed with DCM for 30 s. Quantitative ninhydrin test indicated>99% coupling. The resin was then dried under vacuum. Yield:1.49 g (new loading: 0.661 mmol/g, 0.984 mmol) yellowish resin.550 mg (0.661 mmol/g, 0.363 mmol) of the dried acylated resinwas then swollen in 10 mL of anhydrous THF for 1 h. 5 equiv ofKSeCN (262 mg, 1.82 mmol) were added to the swollen resin inTHF. The mixture was then incubated under argon atmosphere at45 C and gently agitated for 22 h (magnetic stirring should be avoided as the stir bar will crush the resin which will later clog theSPPS synthesis vessel frits). The resin was drained and washed extensively with THF and DCM and dried under vacuum. Yield:452 mg (new loading: 0.67 mmol/g, 0.303 mmol) of greyish-whiteresin.The dried resin (450 mg, 0.3 mmol) was re-swollen in 8 mL ofTHF for 1 h, cooled to 0 C on an ice/water bath, and sodium borohydride(37.83 mg, 1 mmol) in 95% (v/v) EtOH/H2O (1 mL) wasadded in one portion. The reaction was placed at 0 C for 1 h withoccasional agitation, drained, and washed with THF, DCM, andDMF.Prior to coupling of the first amino acid, the resin was treatedwith 3 mmol 1,4-dithiothreitol (DTT) in 6 mL DMF for 10 min.The resin was then drained, and without washing, a 10 equivpre-activated mixture of Boc-Xaa-OH (3 mmol), HATU (1140 mg,3 mmol), and 1.038 mL DIEA (6 mmol) in 6 mL of DMF was addedand allowed to couple for 1 h. The resin was then drained andwashed with DMF, and the reduction and coupling steps were performeda second time. The resin was washed with DMF and stepwisesynthesis was subsequently carried out using standard Boc in-situ neutralization protocols as described previously.

YieldReaction ConditionsOperation in experiment
10.2% The titled peptide was synthesized on a model 430A peptide synthesizer (Applied Rio systems, Foster City, Calif., U.S.A.) which was modified to do accelerated Hoc-chemistry solid phase peptide synthesis (Schnolzer, M. et al., mt. J Peptide Protein Res., (1992), 40:180). 4-Methylbenzhydry- lamine (MHHA) resin (Peninsula, Helmont, Calif., U.S.A.), with a substitution of0.91 mmol/g was used. Hoc amino acids (Midwest Hio-Tech, Fishers, Ind., U.S.A.; Novabiochem., San Diego, Calif., U.S.A.) were used with the following side chain protection: Hoc-Ala-OH, Hoc-Arg(Tos)-OH, Hoc-His (DNP)-OH, Hoc-Val-OH, Hoc-Ecu-OH, Hoc-Gly-OH, HocGln-OH, Hoc-Eys(2C1Z)?--OH, Hoc-Ser(Hzl)-OH, Hoc-PheOH, Hoc-Glu(OcHex)-OH and Hoc-Pro-OH. Fmoc-Glu (OtHu)-OH (Novabiochem, San Diego, Calif., U.S.A.) was used for the residue at the 3rd position in the sequence. The synthesis was carried out on a 0.25 mmol scale. The Hoc groups were removed by two treatments with 100percent TFA each lasting one minute. Hoc amino acids (2.5 mmol) were preactivated with HH11J (2.0 mmol) and DIEA (1.0 mE) in 4 mE of DMF and were coupled without prior neutralization of the peptide-resin TFA salt. Coupling times were 5 minutes. At the end of the assembly of the first 25 residues on theAHI 430A® peptide synthesizer and before the coupling of Fmoc-Glu (OtHu)-OH, the protected peptide-resin was transferred into a reaction vessel on a shaker for manual synthesis. After removing the Hoc protecting group with two, one-minute treatments with 100percent TFA and a washing with DMF, the resin was mixed with Fmoc-Glu(OtHu)-OH (2.5 mmol) which was preactivated with HHTU (2.0 mmol), HOHt (2.0 mmol) and DIEA (1.0 mE) in 4 mE of DMF. The mixture was shaken for 2 hours. This coupling step was repeated. After washing with DMF, the resin was treated with a TFA solution containing 5percent water and 5percent TIS for 2 hours to remove the tHu protecting group in the side chain of the Glu residue. The resin was neutralized with 10percent DIEA in DMF and washed with DMF and DCM. The resin was then treated twice with hexylamine (2.0 mmol), DIC (2.0 mmol), HOHt (2.0 mmol) in 5 ml of DCM for two hours per treatment. The resin was washed with DMF and treated with 25percent piperidine in DMF for 30 minutes to remove the Fmoc protecting group. Afier washing with DMF and DCM, the resin was transferred into the reaction vessel on the AHI 430A peptide synthesizer for the assembly of the rest two residues. At the end of the assembly of the whole peptide chain, the resin was treated with a solution of 20percent mercaptoethanol/10percent DIEA in DMF for 2x30 mm to remove the DNP group on the His side chain. The N-terminal Hoc group was then removed by two treatments of 100percent TFA for 2 minutes. The peptide-resin was washed with DMF and DCM and dried under reduced pressure. The final cleavage was done by stirring the peptide-resin in 10 mE of HF containing 1 mE of anisole and dithiothreitol (50 mg) at 0° C. for 75 minutes. HF was removed by a flow of nitrogen. The residue was washed with ether (6x 10 mE) and extracted with 4N HOAc (6x10 mE). This crude product was purified on a reverse-phase preparative HPEC using a colunm (4x43 cm) of C18 DYNAMAX-100A°® (Varian, Walnut Creek, Calif., U.S.A.). The column was eluted with a linear gradient from 75percentAand25percent B to 55percentAand45percent B at flow rate of 10 mE/mm in an hour where A was 0.1percent TFA in water and B was 0.1percent TFA in acetonitrile. Fractions were collected and checked on an analytical HPEC. Those containing pure product were combined and lyophilized to dryness. 31.8 mg of a white solid was obtained. Purity was 89percent based on analytical HPEC analysis. Electro-spray ionization mass spectrometry (ESI MS) analysis gave the molecular weight at 3368.4 (in agreement with the calculated molecular weight of 3368.9).
