Reaction Steps

A solution of 4.89 g. of 2,4-dimethylphenylisocyanate in 100 ml. of hexane is added to a solution of 3.48 g. of di(n-butyl)amine 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-di-(n-butyl)-3-(2,4-dimethylphenyl)urea, m.p. 48°-50° C.
