Procedure
4-Methoxy-3-thiopheneamine (11 g, 0.085 mol) and ethyl 2-butyryl-3-ethoxyprop-2-enoate (20 g, 0.093 mol) was heated in an inert atmosphere at 120° for 30 minutes. Addition of petroleum ether, b.p. 40°-60°, 200 ml, gave a solid which was collected by filtration and dried, 17.58 g, m.p. 89°-91°.
