(E)-4-chloro-2-methoxy-1-(2-nitrovinyl)benzene (245 mg, 1.15 mmol) was diluted with THF (1 mL), placed under nitrogen and cooled to 0° C. LAH (4588 μL, 4.59 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 174 μL of water, 174 μL of 15% NaOH and 522 μL water. After stirring for 1 hour, ethyl acetate and MgSO4 was added. The reaction mixture was filtered and concentrated to yield 2-(4-chloro-2-methoxyphenyl)ethanamine (160 mg, 0.862 mmol, 75.1% yield).
