실험 절차

A suspension of 5.2 g. of phthalic anhydride in 75 ml. of chloroform is stirred and treated with 5.7 g. of 2-(1-methylhydrazino)benzoxazole. A clear yellow solution results and the temperature drops several degrees, then rises to 33+ C. After about 15 min. precipitation of a solid begins. An additional 200 ml. of chloroform is added and the mixture is stirred overnight. The solid is filtered, washed with chloroform and dried to give 8.6 g. of product, m.p. 140°-142°.
