Versuchsvorschrift

4-(4-((R)-(tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)-N-(4-((R)-4-morpholino-1-(phenylthio)butan-2-ylamino)-3-nitrophenylsulfonyl)benzamide (INTERMEDIATE 75, 329.0 mg, 0.33 mmol) was charged in a 100 ml flask under nitrogen and treated with TBAF (10.0 ml, 1.0 M in THF, 10 mmol). The resulting solution was stirred at room temperature for 35 minutes whereupon the volatiles were removed under reduced pressure. The concentrate was diluted with DCM (100 ml) and washed with 1N aq. NaHSO4 (100 ml), and saturated aq. NaHCO3 (30 ml), then dried (Na2SO4), filtered, and evaporated under vacuum. The concentrate was purified by column chromatography (ISCO, 12 g silica gel column, eluting with 0→5% MeOH/DCM) followed by further purification by column chromatography (ISCO, 12 g silica gel column, eluting with 0→90% DCM/[10% of 2M NH3 in MeOH/90% DCM]) to provide the title product (228 mg, yield: 78%)
