Reaction Steps

(4S,7S,10aS)-Methyl 4-((2R,5R)-2,5-dibenzyl-6-((4R,10aR)-1,5-dioxodecahydropyrido[1,2-a][1,4]diazepin-4-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 (20 mg, 0.035 mmol) and Intermediate 39 (7.0 mg, 0.035 mmol) to give a white solid (15 mg, 56% yield).
