실험 절차

In 10 ml of methanol is dissolved 3-(2-tert-butoxycarbonylamino-3-methylaminocarbonyloxypropoxy)-5-chloro-1,2-benzoisoxazole, and to this solution is added 9.6 ml of a 2-propanol solution (7.5N) of hydrogen chloride, and they are subjected to reaction at 20°-25° C. for 4.5 hours. The solvent is removed from the reaction mixture by distillation under reduced pressure, and to the residue obtained is added 5 ml of 2-propanol, after which the crystals precipitated are collected by filtration, to obtain 0.30 g of colorless, crystalline 3-(2-amino-3-methylaminocarbonyloxypropoxy)-5-chloro-1,2-benzoisoxazole hydrochloride having a melting point of 206°-209° C.
