Procedure
To a solution of (R)-4-(4-((tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid (INTERMEDIATE 13, 183 mg, 0.34 mmol) in DCM (3 ml) were added sequentially DMAP (125 mg, 1.02 mmol), 4-((R)-4-((S)-3-((tert-butyldiphenylsilyloxy)methyl)morpholino)-1-(phenylthio)butan-2-yl amino)-3-(trifluoromethylsulfonyl)benzenesulfonamide (INTERMEDIATE 105, 280 mg, 0.34 mmol) and EDC (131 mg, 0.68 mmol). The resulting solution was stirred at room temperature overnight. Evaporation of the volatiles under reduced pressure gave a residue which was purified by column chromatography (ISCO, 27 g silica gel column, eluting with 0→20% EtOAc/hexanes) to give 4-(4-((R)-(tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)-N-(4-((R)-4-((S)-3-((tert-butyldiphenylsilyloxy)methyl)morpholino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonyl)benzamide (EXAMPLE 24, STEP 1,153 mg) which was used in the preparation of EXAMPLE 24, STEP 2 without further purification.
