A solution of di-tert-butyl 2-(((R)-3-(4-(N-(4-(4-((R)-(4′-chlorobiphenyl-2-yl)(hydroxy)methyl)piperidin-1-yl)benzoyl)sulfamoyl)-2-(trifluoromethylsulfonyl)phenylamino)-4-(phenylthio)butyl)(methyl)amino)ethyl phosphate (INTERMEDIATE 56, 140 mg, 0.13 mmol) in DCM (3 ml) was treated with a solution of HCl (4M in dioxane, 0.6 ml). When the addition was completed, a white precipitate was observed. The mixture was diluted with MeOH after an hour and the volatiles were evaporated under reduced pressure to give a gummy residue. The material was dissolved in MeOH, and diluted with ˜20 ml DCM, resulting in a white precipitate. The mixture was concentrated under reduced pressure to provide a white solid. The material was triturated in 10-15 ml CH2Cl2, and dried under high vacuum to provide the title compound (120 mg, yield: 95%).
