(R)-4-((4-(Dimethylamino)-1-(phenylthio)butan-2-yl)amino)-3-nitrobenzenesulfonamide → 4-(4-((R)-(tert-butyldimethylsilyloxy)(4'-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)-N-(4-((R)-4-(dimethylamino)-1-(phenylthio)butan-2-ylamino)-3-nitrophenylsulfonyl)benzamide

Participants

Reaction Steps

The title product (162.8 mg, yield: 32%) was prepared using a procedure similar to the one described for the synthesis of INTERMEDIATE 32 utilizing (R)-4-(4-((tert-butyldimethylsilyloxy)(4 ′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid (INTERMEDIATE 13, 249.6 mg, 0.47 mmol) and (R)-4-(4-(dimethylamino)-1-(phenylthio)butan-2-ylamino)-3-nitrobenzenesulfonamide (INTERMEDIATE 19, 208.8 mg, 0.49 mmol). The title product was purified by column chromatography (ISCO, 12 g silica gel column, eluting with 0→10% MeOH/DCM).
