Reaction Steps

A suspension of 4-(6-methyl-5-nitro-2-pyridinyl)morpholine (500 mg, 2.240 mmol), iron powder (375 mg, 6.72 mmol) and ammonium chloride (60 mg, 1.120 mmol) in ethanol (15 mL) and water (5 mL) was heated at reflux for 2 hours. The reaction mixture was filtered through a pad of celite and the pad washed with further ethyl acetate. The combined filtrate and washings were separated between ethyl acetate and saturated sodium bicarbonate and the organic phase was washed with water then brine. The organics were then separated, dried over magnesium sulphate and evaporated in vacuo to give the title compound (171 mg) as a pale brown solid. LCMS (2 min, formic) Rt 0.30 min, m/z (ES+) 194 (M+H).
