Reaction Steps

(4S,7S,10aS)-Methyl 4-((2R,5R)-2,5-dibenzyl-6-((S,Z)-1-benzyl-2-oxo-1,2,3,4,7,8-hexahydroazocin-3-ylamino)-6-oxohexanamido)-5-oxooctahydro-2H-pyrido[2,1-b][1,3]thiazepine-7-carboxylate was synthesized as described in General Procedure H using Intermediate 23 (8.0 mg, 0.014 mmol) and Intermediate 44 (6.5 mg, 0.028 mmol) to give a white solid (6.8 mg, 61% yield).
