Reaction Steps

Ammonium chloride (1.2 g, 23.0 mmol) in water (4.5 mL) then MeOH (9 mL) were added to a stirred solution of 4-(4-nitro-phenyl)-morpholine (480 mg, 2.3 mmol) in THF (9 mL). Zinc powder (1.2 g, 18.4 mmol) was then added portion wise and the resulting mixture was stirred at room temperature for 15 minutes. The reaction mixture was filtered over celite and the filtrate was extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4 and concentrated to afford 316 mg (77%) of 4-morpholin-4-yl-phenylamine. 1H NMR: (DMSO-d6): δ 6.7 (m, 2H), 6.5 (m, 2H), 4.6 (s, 2H), 3.7 (t, 4H), 2.8 (t, 4H).
