反応手順

Into a slurry of 19.7 g of benzanilide (m.p. 162°-164° C.) in 200 ml of methylene chloride was added a solution of 12.0 g of thionylchloride in 50 ml of methylene chloride. After the addition was completed and the reaction mixture was stirred for one hour at room temperature, gaseous dimethylamine was introduced until the solution became saturated. Workup by filtration, waterwash, removal of the solvent and distillation afforded N,N-dimethyl-N'-phenylbenzamidine in 18.6 g or 83% yield.
