Reaction Steps

To a solution of 336 mg (0.481 mmol) of 3-[({1-[5-(5-tert-Butyl-3-methanesulfonylamino-2-methoxy-phenylcarbamoyl)-2-methyl-phenyl]-1H-[1,2,3]triazole-4-carbonyl}-amino)-methyl]-piperidine-1-carboxylic acid tert-butyl ester (Example 72) in 5 mL CH2Cl2 was added dropwise 1.2 mL of 4N HCl in dioxane. As a gummy yellow precipitate began to form in the flask, 10 drops of MeOH were added and the solution was stirred overnight. The mixture was partitioned between CH2Cl2 (75 mL) and 50% saturated aqueous NaHCO3 (50 mL). The layers were separated and the aqueous portion was extracted with CH2Cl2 (2×30 mL). The combined extracts were washed with water (30 mL), brine (30 mL), dried (Na2SO4), filtered and concentrated to afford 190 mg of 1-[5-(5-tert-Butyl-3-methanesulfonylamino-2-methoxy-phenylcarbamoyl)-2-methyl-phenyl]-1H-[1,2,3]triazole-4-carboxylic acid (piperidin-3-ylmethyl)-amide as a pale yellow solid.
