Procedure

A 1.38 g. amount of sodium metal is dissolved in 150 ml. of absolute ethanol, then 8.1 g. of m-fluorophenylhydrazine hydrochloride is added followed by 3.9 g. of methacrylonitrile. The reaction mixture is refluxed for 5 hours, then is evaporated to dryness in vacuo. Water is added to give a dark semi-solid precipitate. The aqueous is decanted then more water is added and the solid is collected by filtration. The solid is dissolved in dichloromethane and the solution is passed through a short column of a hydrous magnesium silicate. The effluent is evaporated to give an oil. The oil is dissolved in hexane, treated with activated charcoal and filtered and evaporated to give a solid. The solid is recrystallized from hexane to give 0.65 g. of the desired product as light orange prisms, m.p. 78°-80° C.
