Procedure

After dissolving 4.9 g. (0.05 mole) of 2-imino-1-methylpyrrolidine in anhydrous benzene, 5.96 g. (0.05 mole) of phenylisocyanate is added dropwise with stirring (heat evolves). The reaction mixture is stirred for one-half hour. The solid product which is formed, 1-(1-methyl-2-pyrrolidylidene)-3-phenylurea, is collected (m.p. = 140°-144° C); recrystallized from methanol to give the pure product, m.p. = 146°-147.5° C.
