YieldReaction ConditionsOperation in experiment
50.5% Stage #1: [(2S,5R,8S,11S)-8-(4-Amino-butyl)-11-(3-guanidino-propyl)-5-(4-hydroxy-benzyl)-3,6,9,12,15-pentaoxo-1,4,7,10,13-pentaaza-cyclopentadec-2-yl]-acetic acid; 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid mono(N-hydroxysuccinimidyl ester) With O-(N-succinimidyl)-N,N,N',N'-tetramethyluronium tetrafluoroborate; N-ethyl-N,N-diisopropylamine In 1-methyl-pyrrolidin-2-one at 20℃; for 4h; Stage #2: lanthanum nitrate In 1-methyl-pyrrolidin-2-one Compound (12): c(RGDyK)-(DOTA-La). Compound (12): c(RGDyK)-(DOTA-La). To a solution of NHS-DOTA (Macrocyclics), (2.0 mg, 3.14×10-3 mmol) dissolved in NMP (1.0 mL), the targeting peptide c(RGDyK) (Peptides, International) (1.95 mg, 3.14×10-3 mmol) in NMP (1.0 mL) with DIPA (4.07 mg, 3.15×10-2 mmol) and TSTU (1.90 mg, 6.30×10-3 mmol) was added. The solution was stirred for 4 h at room temperature while using LC-MS method B: 5-100% to check the reaction progress. Once the reaction was complete, the solid La(NO3)2 (3.41 mg, 7.87 mmol) was added, again following by LC-MS method B: 5-100% to check the reaction progress which was immediate. Diethyl ether (5 mL) was added to precipitate the product which was vortexed and centrifuged in a 15 mL centrifuge tube This product was purified through SPE using method B: 5-50% with product found in fractions 5-20%. Yield: 1.2 mg (1.03×10-3 mmol, 50.5%); LC-MS=Calcd. for C43H64LaN13O15: 1141.37 (m/z). found: 1140.40 [M-H]-; 570 [(M-2H/2]-.
