A solution of 30 mL ethyl acetate, 175 mL ethanol, and 2.50 g of 2-(4-Fluoro-2-nitrophenylamino)-N-isopropyl-N-(4-methoxy-phenyl)-acetamide (6.92 mmol) was combined with 0.25 g of palladium on carbon (10 wt %) and hydrogenated under a hydrogen balloon over 16 hrs. The reaction mixture was filtered and evaporated in vacuo to provide 1.91 g of the title compound as a solid. 1H NMR (300 MHz, CDCl3) d 7.03 (m, 2H), 6.94 (m, 2H), 6.36 (m, 3H), 4.99 (m, 1H), 4.37 (b, 3H), 3.86 (s, 3H), 3.39 (s, 2H), 1.07 (d, 6H, J=6.8); low resolution MS (FAB)m/e 332 (MH+).
