Reaction Steps

(4S,7S,10aS)-Methyl 4-((2R,5R)-2,5-dibenzyl-6-oxo-6-((S,Z)-2-oxo-1-phenyl-1,2,3,4,5,8-hexahydroazocin-3-ylamino)hexanamido)-5-oxooctahydro-2H-pyrido[2,1-b][1,3]thiazepine-7-carboxylate was synthesized as described in General Procedure H using Intermediate 23 (11 mg, 0.019 mmol) and Intermediate 63 (5.6 mg, 0.022 mmol) to give a white solid (3.5 mg, 25% yield).
