Procedure

500 mg of [[(S)-3-[(S)-1-tert-butoxycarbonyl-piperidin-3-ylmethylcarbamoyl]-2-(naphthalen-2-sulfonylamino)-propionyl]cyclopropyl-amino]-acetic acid are stirred at room temperature for 20 hours in 10 ml of methylene chloride together with 71 mg of O-methylhydroxylamine hydrochloride, 0.28 ml of N-methylmorpholine and 376 mg of BOP. The mixture is taken up in ethyl acetate and washed with 1N hydrochloric acid and then with water. After drying and evaporation the product is purified over silica gel with ethyl acetate/methanol (9:1). There are obtained 282 mg of tert-butyl (S)-3-[(S)-3-([cyclopropyl-methoxycarbamoylmethyl-carbamoyl)]-3-(naphthalen-2-ylsulfonylamino)-propionylaminomethyl]-piperidine-1-carboxylate, MS (ISP): 646.6 (M+H).
