Hydrochloric Acid → 3-(2-Amino-3-hydroxypropoxy)-5-chloro-1,2-benzoisoxazole hydrochloride

Participants

Reaction Steps

To a solution of 7.68 g of 3-[(3-tert-butoxycarbonyl-2,2-dimethyloxazolidin-4-yl)methoxy]-5-chloro-1,2-benzoisoxazole in 77 ml of chloroform and 77 ml of methanol is added 16 ml of a 2-propanol solution (7.5N) of hydrogen chloride at 20°-25° C., and they are subjected to reaction at the same temperature overnight. The crystals precipitated are collected by filtration, to obtain 4.47 g of 3-(2-amino-3-hydroxypropoxy)-5-chloro-1,2-benzoisoxazole hydrochloride.
