Reaction Steps
To a solution of 8.80 g. of 4-fluorophenylhydrazine hydrochloride in a mixture of 10.9 ml. of 5 N sodium hydroxide, 100 ml. of 30% aqueous acetic acid and 50 ml. of p-dioxane is added 10.0 g. of N-(dimethylaminomethylene)-p-nitrobenzamide. The reaction mixture is stirred and heated at 90° C. for 1.5 hours, then poured into 200 ml. of water. The solid is collected and recrystallized from ethanol, giving 10.4 g. of the desired product as yellow crystals, mp. 132°-134° C.
