Reaction Steps
To a suspension of monoethyl potassium epoxysuccinate (1.7 g) in ethyl ether (30 ml), oxalyl chloride (1.2 g) in ethyl ether was added dropwise with stirring under ice-cooling and the mixture was stirred for an hour at room temperature. To the reaction mixture, aniline (1.6 g) in ethyl ether was added dropwise with stirring under ice-cooling, and the mixture was stirred at room temperature for an hour. The precipitate produced was filtered off and the filtrate was washed with a saturated aqueous sodium chloride solution, dried over magnesium sulfate and concentrated to dryness. The crude product was purified by chromatography using silica gel as an absorbent and benzene as an eluent, and then recrystallized from n-hexane-acetone to give 1.0 g of ethyl N-phenyl-2,3-epoxysuccinamate (Compound No. 1). m.p. 83°-84° C.
