Procedure

A mixture of 15.0 g of 1-(3-methyl-2-thienyl)-2-(2-nitrophenyl)ethanone oxime, 27 ml of pyridine and 14 ml of acetic anhydride was heated on a steam bath for 0.5 hr, with stirring. The solution was decanted into ice-water. The solid was collected and recrystallized from 95% ethanol to give 14.8 g of product, mp 60°-68° C.
