実験手順
(E)-2-chloro-1-(2-nitrovinyl)-4-(trifluoromethyl)benzene (160 mg, 0.636 mmol) was diluted with THF (1 mL), placed under nitrogen and cooled to 0° C. LAH (2544 μL, 2.54 mmol) was added dropwise and the reaction was stirred for 5 hours warming to ambient temperature. The reaction was cooled to 0° C. and quenched with 100 μL of water, 100 μL of 15% NaOH and 300 μL water. After stirring for 1 hour, ethyl acetate and MgSO4 was added. The reaction mixture was filtered and concentrated to yield 2-(2-chloro-4-(trifluoromethyl)phenyl)ethanamine (60 mg, 0.268 mmol, 42.2% yield).
