Reaction Conditions

Reaction Steps

To a solution of methyl(2E)-3-(4-methoxy-2-nitrophenyl)acrylate (Intermediate 5, 4.9 g, 20.66 mmol) in acetic acid (150 mL) at room temperature under nitrogen was added zinc powder (7.7 g, 118 mmol) in portions. After 4 hours, another 5 g of zinc was added and the resulting reaction mixture was heated at 50° C. for two hours. The reaction mixture was then cooled to room temperature, filtered, and the filtrate was concentrated to dryness under reduced pressure. The residue was chromatographed on silica gel with hexanes/ethyl acetate (3:1) to give 1.0 g (23% yield) of product as a yellow solid, mp 149° C.
