Procedure

10% Pd/C (100 mg) is added to a Parr bottle containing 1-(3-ethylamino-4-nitro-phenyl)-ethanone (0.98 g, 4.7 mmol) in ethanol (40 mL). The Parr bottle is sealed in a mechanical shaker, evacuated, and then purged with nitrogen followed by hydrogen. The system is pressurized to 50 PSI of hydrogen at room temperature and mechanical shaking engaged. After 2 hours, shaking is stopped, and the system purged with nitrogen prior to opening the vessel. The reaction mixture is filtered through celite, concentrated in vacuo, to give 1-(4-amino-3-ethylamino-phenyl)-ethanone.
