Participants

Reaction Steps

Ethyl 2-(6-(cyclopropylmethoxy)-5-nitro-4′-(trifluoromethyl)biphenyl-3-yl)-4-methylpentanoate (300 mg, 0.626 mmo) was taken in 30 ml of Toluene:Water (1:1) and to it added Fe powder (203 mg, 3.62 mmol), Ammonium formate (228 mg, 3.62 mmol). The reaction mixture was refluxed for 3 h and then filtered through celite. The toluene was distilled off under reduced pressure and the crude residue was purified by column chromatography using Ethyl acetate:hexane (2:3) as eluent provided 220 mg of ethyl 2-(5-amino-6-(cyclopropylmethoxy)-4′-(trifluoromethyl)biphenyl-3-yl)-4-methylpentanoate. 1H NMR (CDCl3): δ 7.40-7.20 (m, 5H), 6.90 (s 1H), 4.50 (bs, 2H), 4.15 (q, 2H), 3.60 (t, 1H), 3.45 (d, 2H), 1.95-2.00 (m, 1H), 1.75-1.80 (m, 1H), 1.45-1.50 (m, 1H), 1.20 (t, 3H), 1.00 (m, 6H), 0.35-0.25 (m, 5H). Mass: (450, M+1, 100%).
