Procedure

The title product (110 mg, yield: 88%) was prepared using a procedure similar to the one described for the synthesis of INTERMEDIATE 32 utilizing 4-(4-((tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid (INTERMEDIATE 13, 56.7 mg, 0.11 mmol) and (R)-4-(4-((2-(tert-butyldiphenylsilyloxy)ethyl)(methyl)amino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)benzenesulfonamide (INTERMEDIATE 28, 75 mg, 0.10 mmol) as starting materials. The title product was purified by column chromatography (ISCO, 12 g silica gel column, eluting with 0→30% EtOAc/hexanes).
