DCM (3.0 ml) and DIPEA (0.08 ml, 0.46 mmol) were added and the solution was stirred at r.t for 15 min. A solution of (R)-4-(4-((2-(tert-butyldiphenylsilyloxy)ethyl)(methyl)amino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)benzenesulfonamide (INTERMEDIATE 28, 0.178 g, 0.23 mmol) in DCM (1.5 ml) was added to the solution and the reaction mixture was stirred at r.t overnight. The reaction mixture was diluted with DCM and washed with sodium bisulfate (1N, aq.) followed by a sodium bicarbonate (saturated, aq.). The organic layer was dried (Na2SO4), filtered, and evaporated under reduced pressure to give a residue which was dried under vacuum to provide N-(4-((R)-4-((2-(tert-butyldiphenylsilyloxy)ethyl)(methyl)amino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonyl)-4-(4-((R)-(4′-chlorobiphenyl-2-yl)((S)-1,1-dimethylethylsulfinamido)methyl)piperidin-1-yl)benzamide (EXAMPLE 11, STEP 1, 0.26 g) which was used in the preparation of EXAMPLE 11, STEP 2 without further purification.
