Reaction Steps

To a mixture of 1-(benzyloxy)-2-cyclopentyl-5-nitro-4-(trifluoromethyl)benzene (3.0 g, 8.2 mmol) and Fe (2.8 g, 49.3 mmol) in 25% aqueous ethanol (40 mL) was added concentrated HCl (2.1 g, 1.8 mL, 58.7 mmol). The mixture was stirred at 50° C. for 4 h. The reaction was filtered hot and washed with ethanol (2×5 mL). The filtrate was concentrated to ˜20 mL volume, resulting in the precipitation of a yellow crystalline solid. The solid was filtered, washed with water and dried to provide 5-(benzyloxy)-4-cyclopentyl-2-(trifluoromethyl)aniline as a yellow-brown crystalline solid (3.0 g, 98% yield). NMR (400.0 MHz, CDCl3) δ 7.40-7.35 (m, 5H), 7.25 (d, J=6.7 Hz, 1H), 6.24 (s, 1H), 5.06 (s, 2H), 4.03 (s, 2H), 3.28-3.20 (m, 1H), 1.99-1.95 (m, 2H), 1.74-1.65 (m, 2H), 1.67-1.62 (m, 2H), 1.58-1.54 (m, 2H).
