Reaction Steps

To a suspension of sodium borohydride (4 g) in a mixture of dioxane (85 ml) and ethanol (30 ml) was added dropwise a solution of 2-(2-nitroethenyl)naphthalene (100 g) in dioxane (90 ml) over 30 minutes. The flask was cooled with a cold water bath during addition. Stirring was maintained for an additional 11/2hours. Ice (100 ml) and 50% aqueous acetic acid room temperature, concentrated in vacuo and extracted with methylene chloride. The organic layer was washed with water, saturated aqueous sodium chloride and dried over magnesium sulfate. The solvent was evaporated in vacuo to yield an oil which was crystallized from acetic acid to give the title compound (6.79 g) as a yellow solid, m.p. 59°-60° C.
