(R)-4-(4-((tert-Butyldimethylsilyloxy)(4'-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid → HCID 86661879, compound

Participants

Reaction Steps

The title product (134 mg, yield: 77%) was prepared using a procedure similar to the one described for the synthesis of INTERMEDIATE 33. (R)-4-(4-((tert-Butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid (INTERMEDIATE 13, 67.7 mg, 0.13 mmol) and 4-((R)-4-((R)-3-((tert-butyldiphenylsilyloxy)methyl)morpholino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)benzenesulfonamide (INTERMEDIATE 109, 94.4 mg, 0.11 mmol) were used as starting materials. The resulting product was purified by column chromatography (ISCO, 12 g silica gel column, eluting with 0→30% EtOAc/hexanes), providing the title compound.
