Procedure

(R)-4-(4-((tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid (INTERMEDIATE 13, 56.5 mg, 0.11 mmol), (R)-4-(4-(4-(2-(tert-butyldiphenylsilyloxy)ethyl)piperazin-1-yl)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)benzenesulfonamide (INTERMEDIATE 22, 80 mg, 0.1 mmol), DMAP (35.1 mg, 0.29 mmol), and EDC (36.7 mg, 0.19 mmol) were placed in a 50 ml flask and flushed with nitrogen. DCM (0.96 ml) was added, and the solution was stirred at room temperature overnight. The reaction mixture was diluted with DCM (40 ml) and washed with 1N sodium bisulfate (35 ml) followed by a saturated aq. sodium bicarbonate (40 ml). The organic layer was dried (Na2SO4), filtered, and evaporated under reduced pressure to give the title product (147 mg, yield: quantitative), that was used in the preparation of EXAMPLE 1 without further purification.
