反应详情

Acetic acid (13 mL) was added slowly to a mixture of zinc dust (12.4 g) and 2-chloro-4-nitro-6-trifluoromethyl-phenylamine (4 g) in tetrahydrofuran (40 mL). The reaction mixture was stirred for 1 hour, filtered through silica and concentrated in vacuo. The crude product was purified by flash chromatography to furnish 2.9 g (83%) of the title compound as a black solid. 1H NMR (500 MHz, CDCl3): 3.44 (b, 2H), 4.16 (b, 2H), 6.77 (d, 1H), 6.86 (d, 1H).
