Procedure

To a mixture of 4-[[4-methoxybenzenesulfonyl](benzyl)amino]-1-[benzyl]-4-[carboxy]-piperidine (850.0 mg, 1.64 mmol) in methylene chloride (100 mL) containing N-methylmorpholine (0.6 ml, 5.48 mmol) and O-t-butylhydroxyl amine hydrochloride (620.0 mg, 4.94 mmol) is added N-[dimethylaminopropyl]-N'-ethylcarbodiimide hydrochloride (1.1 g, 5.74 mmol). The reaction mixture is stirred overnight at room temperature. The mixture is diluted with water and extracted with methylene chloride. The combined organic extracts are dried (Na2SO4) and the solvent is evaporated. The crude product is purified by silica gel chromatography (ethyl acetate) to provide 4-[N-t-butyloxy-carbamoyl]-4-[[4-methoxybenzenesulfonyl](benzyl)amino]-1-[benzyl]-piperidine.
