Reaction Steps
Add sodium borohydride (1.69 g, 44.64 mmol) to 1-benzyloxy-3-fluoro-5-((E)-2-nitro-vinyl)-benzene (3.05 g, 11.16 mmol) and silica gel (22 g) in chloroform (112 mL) and isopropanol (33 mL) at room temperature in portions over 5 minutes. Stir at room temperature 90 minutes and filter. Concentrate and dissolve in ethyl acetate. Wash (10% potassium carbonate and saturated aqueous sodium chloride), dry over magnesium sulfate, filter and concentrate. Purify on 120 g silica gel eluting with 100:0 to 80:20 hexanes:ethyl acetate to afford 1.33 g (43.3%) of the desired compound as an oil.
