Procedure

A solution of TASF (0.46 ml. 0.46 mmol, 1 M in DMF) was added to a solution of N-(4-((R)-4-((2-(tert-butyldiphenylsilyloxy)ethyl)(ethyl)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 12, STEP 1, 0.30 g, 0.23 mmol) in DMF (1.9 ml) and the reaction mixture was stirred at r.t for 1 hour. The reaction mixture was concentrated under reduced pressure, diluted with DCM and washed with H2O. The organic layer was dried (Na2SO4), concentrated under reduced pressure and dried under vacuum to give 4-(4-((R)-(4′-chlorobiphenyl-2-yl)((S)-1,1-dimethylethylsulfinamido)methyl)piperidin-1-yl)-N-(4-((R)-4-(ethyl(2-hydroxyethyl)amino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonyl)benzamide (EXAMPLE 12, STEP 2, 0.28 g) which was used in the preparation of EXAMPLE 12, STEP 3, without further purification.
