Reaction Steps

A portion of lithium borohydride (0.458 g, 21.0 mmol) was diluted with THF (30 mL) followed by the dropwise addition of chlorotrimethylsilane (5.34 ml, 42.1 mmol). After stirring for 15 minutes, argon was bubbled through the reaction mixture for 2 minutes to eliminate trimethylsilane present in the reaction. (E)-2-methoxy-1-(2-nitrovinyl)-4-(trifluoromethyl)benzene (1.3 g, 5.26 mmol) was added portionwise (gas evolution occurred). The reaction was heated to reflux for 2 hours, cooled to 0° C. and carefully quenched with methanol (8 mL). The reaction mixture was concentrated, diluted with dichloromethane and 20% aqueous KOH. The layers were separated and the organic layer was dried over sodium sulfate, filtered and concentrated to yield 2-(2-methoxy-4-(trifluoromethyl)phenyl)ethanamine (1.1 g, 5.02 mmol, 95.4% yield).
