Procedure

A solution of 4.89 g. of 2,4-dimethylphenylisocyanate in 100 ml. of hexane is added to a solution of 5.32 g. of dibenzylamine in 150 ml. of hexane and the solution is stirred at room temperature for 2 hours and then evaporated. The residual solid is recrystallized from pentane to yield 1,1-dibenzyl-3-(2,4-dimethylphenyl)urea, m.p. 124°-126° C.
