Procedure

(R)-4-(4-((tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid (INTERMEDIATE 13, 170 mg, 0.32 mmol), (R)-di-tert-butyl 2-(4-(4-(phenylthio)-3-(4-sulfamoyl-2-(trifluoromethylsulfonyl)phenylamino)butyl)piperazin-1-yl)ethyl phosphate (INTERMEDIATE 61, 275 mg, 0.35 mmol), DMAP (116 mg, 0.95 mmol) and EDC (122 mg, 0.63 mmol) were dissolved in DCM (3.2 ml). The reaction mixture was stirred at r.t. for 72 hours. The mixture was diluted with DCM (10 ml) and washed with NaHCO3 solution (saturated, aq., 5 ml) and brine (5 ml). The collected organic layer was dried over Na2SO4 and concentrated to give the title compound (446 mg, yield: almost quantitative). The title compound was used in the preparation of EXAMPLE 10 without further purification.
