Participants

Reaction Steps

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.
