Reaction Steps

To a solution of 4-(4-((R)-(tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)-N-(4-((2R)-4-(2-((diethylamino)methyl)morpholino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonyl)benzamide, single diastereomer (INTERMEDIATE 117, 199 mg, 0.17 mmol) in dioxane (2.027 ml) was added drop wise HCl (4M in dioxane, 0.430 ml, 1.72 mmol) and the reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was neutralized with Et3N (2 ml), diluted with DCM and filtered. The filtrate was concentrated under reduced pressure and purified by column chromatography (ISCO, eluting with 0→100% DCM to 10% MeOH/0.1% NH3 in DCM) to provide the title product as a substantially separated diastereomer (0.06 g, 30%).
