Procedure
Palladium on carbon (5%, 0.510 g) was added into a solution of 3-ethoxy-4-nitro-benzamide (1.694 g, 8.06 mmol) and ammonium formate (2.17 g, 34.4 mmol) in MeOH (25 mL) at ambient temperature. The solution was stirred for 1 hour, filtered through Celite and washed with MeOH. The filtrate was concentrated in vacuo and triturated from diethyl ether to yield white solid (1.45 g, 100%).
