反応手順
14.7 g of 3,5-dimethylphenylisocyanate were slowly added by a dropper upon stirring at a temperature of 28° C. to a solution of 5.7 g of cyclopropylamine in 200 ml diisopropylether. The formed precipitate was removed by suction after an hour, was washed with a small amount of diisopropylene and finally dried. There were thus obtained 18.9 g of 1-cyclopropyl-3-(3,5-dimethylphenyl)-urea (92.5% of the theoretical value) having a melting point of 169° C.
