Procedure

A solution of 4-(4-((R)-(tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)-N-(4-((R)-4-((S)-3-((diethylamino)methyl)morpholino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonyl)benzamide, (INTERMEDIATE 89, 100 mg, 0.09 mmol) and TBAF (3.5 ml 3.46 mmol, 1 M in THF) was stirred for 45 minutes at room temperature. The solvent was removed under reduced pressure and the residue was taken up in DCM (50 ml). The organic layer was washed successively with 50 ml of water (50 ml) and saturated aqueous sodium bicarbonate (50 ml). The organic phase was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The concentrate was purified by column chromatography (ISCO, eluting with 0→100% DCM/[10% 2N ammonia in MeOH in DCM] over 19 minutes and then eluting with 0→20% MeOH/DCM) to give the title product (43.0 mg, yield: 48%).
