Procedure

N-(t-Butyloxy)-2(R)-[[4-methoxybenzenesulfonyl](benzyl)amino]-6-[(N,N-dimethylglycyl)amino] hexanamide (2.17 g, 3.86 mmol) is dissolved in dichloroethane (12 mL) containing ethanol (0.22 mL, 3.86 mmol), and the reaction is cooled to -10° C. Hydrochloric acid gas is bubbled through this solution for 30 minutes. The reaction is sealed, warmed to room temperature and stirred for 2 days. The solvent is reduced to 1/2 volume by evaporating solvent, and triturated with ether. The resulting solid is removed and dried in vacuo to provide N-hydroxy-2(R)-[[4-methoxybenzenesulfonyl](benzyl)amino]-6-[(N,N-dimethylglycyl)amino] hexanamide hydrochloride, m.p. 105°-108° C.
