실험 절차
The hydrochloride salt of 2-imino-1-methylpyrrolidine (5.52 g., 0.041 mole) is converted to free base in benzene in the usual manner. Then 9.08 g. (0.041 mole) of 2,4,6-trichlorophenylisocyanate [made according to the method of K. Inukai and Y. Maki, Kogyo Kagaku Zasshi, 70 (4), 491-4 (1967)] dissolved in anhydrous benzene is added with stirring. The reaction mixture is stirred for 2 hours and the solvent is evaporated in vacuo to give a solid residue of 1-(2,4,6-trichlorophenyl)-3-(1-methyl-2-pyrrolidylidene)urea. Recrystallizations from ethyl acetate yields the pure product, m.p. = 160°-162° C.
