実験手順

A solution of HCl in dioxane (4M, 11.18 ml, 44.70 mmol) was added slowly to a light yellow solution of N-(4-((R)-4-((2-(tert-butyldimethylsilyloxy)ethyl)(ethyl)amino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonyl)-4-(4-((R)-(4′-chlorobiphenyl-2-yl)(hydroxy)methyl)piperidin-1-yl)benzamide (INTERMEDIATE 66, 2.4 g, 2.24 mmol) in DCM (11.2 ml) at 0° C. Once the addition was complete, the ice bath was removed. The resulting solution was allowed to warm to r.t. and stirred for 1 hour before being concentrated under reduced pressure to half volume and diluted with ethyl acetate. The resulting mixture was washed with sodium bicarbonate (saturated, aqueous) and sodium chloride (saturated, aqueous) before being dried over sodium sulfate, filtered, and concentrated under reduced pressure. The concentrate was purified by column chromatography (ISCO, silica gel, 0→20% methanol in ethyl acetate for 30 min) to provide the title compound (1.64 g, yield: 76%).
