Reaction Steps
A solution of 2-imino-1-methylpyrrolidine (obtained from 6.91 g., 0.051 mole, hydrochloride salt) in benzene is dried over potassium carbonate and filtered. A solution of 1-naphthyl isocyanate (8.45 g., 0.05 mole) in benzene is added by filtration. The mixture is stirred for 11/2 hr. at room temperature and the precipitate separated by filtration. Recrystallization from acetone affords the product, 1-(1-methyl-2-pyrrolidinylidene)-3-(1-naphthyl)urea, m.p. 148°-149° C.
