1-tert-Butoxy-2-(2-nitrovinyl)benzene (685 mg, 3.10 mmol) in tetrahydrofuran (10 ml) was cooled to 0° C. under an argon atmosphere (balloon). Lithium aluminum hydride (1 M in THF) (12384 μL, 12.4 mmol, equivalent to 470 mg) was added dropwise over 5 minutes. The reaction was stirred at 0° C. for 30 minutes and then at ambient temperature 4 hours. The reaction was quenched with 0.470 ml water at 0° C., followed by 0.470 ml 1 N aqueous NaOH at 0° C. After 15 minutes, an additional 1.45 ml water was added and the reaction mixture was warmed to ambient temperature and stirred rapidly for 1 hour, after which ethyl acetate (20 ml) and potassium were added. The reaction mixture was filtered and washed with ethyl acetate. The combined filtrate was concentrated in vacuo to afford the title compound (575 mg, 2.97 mmol, 96.1% yield) as a yellow oil.
