87.7% With potassium carbonate In tetrahydrofuran; water at 0 - 20℃; for 4 h; Example A73 Preparation of Ar2-acetyl-L-lysyl-L-valyl-A^-carbamoyl-Ar-[4-([(2-[(3i?,51S',7i?,8i?)-8-hydroxy-7- {(l£,3£)-5-[(21S,,35',5i?,6i?)-5-[(2Z,41S)-4-hydroxypent-2-enoyl]amino}-3,6-dimethyltetrahydro- 2H-pyran-2-yl]-3-methylpenta-l,3-dien-l-yl}-l,6-dioxaspiro[2.5]oct-5- yl]acetyl}hydrazinyl)carbonyl]oxy}methyl)phenyl]-L-ornithinamide, acetate salt (B222). B227 Step 1. Synthesis of N2-acetyl-N6-(teri-butoxycarbonyl)-L-lysine (B223). To a mixture of N6- (fert-butoxycarbonyl)-L-lysine (22.5 g, 91.5 mmol, 1 eq.) and K2CO3 (63.1 g, 0.457 mol, 5 eq.) in tetrahydrofuran/water (200 mL/200 mL) at 0 °C was added acetyl chloride (8.62 g, 0.109 mol, 1.2 eq.), and the mixture was stirred at rt for 4 h. The mixture was concentrated in vacuo to remove the tetrahydrofuran, and the aqueous layer was adjusted to pH = 1 with 2 M HCI and extracted with EtOAc (100 mL) three times. The extract was washed with brine (100 mL), dried over sodium sulfate and concentrated in vacuo to afford B223 (23.1 g, 87.7 percent) as a yellow oil. Step 2. Synthesis of N2-acetyl-L-lysine hydrochloride salt (B224). To a solution of B223 (23.1 g, 0.080 mmol, 1 eq.) in ethyl acetate (400 mL) at 0 °C was added HC1 (g) in ethyl acetate (250 mL) under nitrogen. The mixture was stirred at rt for 4 h and filtered. The solid was washed with ethyl acetate and dried in vacuo to afford B224 (18.5 g, >100 percent) as a white solid which was used without further purification. Step 3. Synthesis of N2-acetyl-N6-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-lysine (B225). To a mixture of B224 (8 g, 35.6 mmol, 1 eq.) and NaHC03 (5.99 g, 71.3 mmol, 2 eq.) in acetone/water (80 mL/80 mL) at 0 °C was added a solution of Fmoc-Cl (9.41 g, 36.3 mmol, 1.02 eq.) in acetone (80 mL), and the mixture was stirred at rt for 2 h. The mixture was adjusted to pH = 3-4 with 2 N HC1 and extracted with ethyl acetate (100 mL) three times. The extracts were washed with brine (100 mL), dried over sodium sulfate and concentrated in vacuo to give the crude product (7 g) as a yellow oil. To the crude product was added dichloromethane and fert-butylmethyl ether (100 mL), and the suspension was stirred for 30 min and then filtered. The filter cake was dried in vacuo to afford B225 (3.25 g, 22.2 percent) as a white solid. Step 4. Synthesis of N2-acetyl-N6-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-lysyl-L-valyl-N5- carbamoyl-N-[4-(hydroxymethyl)phenyl]-L-ornithinamide (B226). To a mixture of B225 (1.04 g, 2.54 mmol, 1 eq.) in NN-dimethylformamide (20 mL) at 0 °C was added N-methylmorpholine (769 mg, 7.61 mmol, 3 eq.), l -ethyl-3-(3-dimethylaminopropyl) carbodiimide-HCl (632 mg, 3.30 mmol, 1.3 eq.), 1 -hydroxybenzotriazole hydrate (445 mg, 3.30 mmol, 1.3 eq.) and L-valyl-N5-carbamoyl-N-[4- (hydroxymethyl)phenyl]-L-ornithinamide (From WO04010957, 1.01 g, 2.66 mmol, 1.05 eq.) under nitrogen, and the mixture was stirred at rt for 2 h. the mixture was poured into teri-butylmethyl ether (300 mL) and filtered. The solid was washed with dichloromethane (50 mL) and water (50 mL) and dried in vacuo to afford B226 (1.87 g, 95.6percent) as a white solid. Step 5. Synthesis of N2-acetyl-N6-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-lysyl-L-valyl-N5- carbamoyl-N-[4-( [(4-nitrophenoxy)carbonyl]oxy}methyl)phenyl]-L-ornithinamide (B227). To a mixture of B226 (1.87 g, 2.43 mmol, 1 eq.) and bis-(4-nitrophenyl)carbonate (2.21 g, 7.28 mmol, 3 eq.) in NN-dimethylformamide (30 mL) at 0 °C was added NN-diisopropylethylamine (313 mg, 2.43 mmol, 1 eq.) under nitrogen, and the mixture was stirred at rt overnight. The mixture was poured into teri-butylmethylether (50 mL) and filtered. The solid (1.95 g) was purified by prep HPLC to give B227 (580 mg, 25.7 percent) as a white solid. lU NMR (400Hz, DMSO-dg): 10.1 (s, 1 H), 8.29 (d, 2 H), 8.00 (d, 1 H), 7.86 (d, 1 H), 7.65 (d, 2 H), 7.64 (d, 1 H), 7.61 (m, 4 H), 7.40 (m, 2 H), 7.38 (m, 4 H), 7.30 (m, 3 H), 6.01 (br, 1 H), 5.21 (s, 2 H), 4.35 (br, 1 H), 4.27-4.15 (m, 5 H), 2.96 (m, 4 H), 1.98 (m, 1 H), 1.82 (s, 3 H), 1.65 (br, 3 H), 1.43-1.24 (m, 7 H), 0.83 (m, 6 H). Step 6.
