Procedure

To a heated solution of 6-nitroveratraldehyde (84 g, 0.4 mole), 500 ml oftoluene, and 1 ml of acetic acid was added a suspension of 2-aminothiazole (50 g, 0.44 mole) and 250 ml of toluene. The material was refluxed until 7 ml of water was collected using a Dean-Stark apparatus. The solid was removed and the filtrate was concentrated leaving a light solid which was recrystallized from benzene to yield 84 g (71%) of the product, m.p. 125°-130°.
