반응 단계
The HBF4 salt of 1,5-dimethyl-2-iminopyrrolidine (6.75 g.; 0.0337 mole) is converted to free base in benzene in the usual manner. Then 4.96 g. (0.0337 mole) of 2,6-dimethylphenylisocyanate, dissolved in anhydrous benzene, is added. The reaction mixture is stirred for 2 hours and then the solvent is evaporated in vacuo leaving an oily residue which eventually crystallizes. Recrystallization from ethyl acetate gives the product, 1-(2,6-dimethylphenyl)-3-(1,5-dimethyl-2-pyrrolidylidene)urea, m.p. 120°-122° C.
