Procedure
Methyl 5-(morpholin-4-ylcarbamoyl)thiophene-2-carboxylate (237 mg, 0.87 mmol) in ethanol (6.0 mL) was refluexed with heating with hydrazine monohydrate (0.40 mL) for 6 hours and allowed to cool to room temperature and the solvent was evaporated at 40° C. 5 mL of diethyl ether was added to the resulting oil, and the precipitated solid was collected by filtration, washed with water and dried to give 160 mg of the desired product (yield 68%).
