To N-methylbenzylamine (12.1 g, 0.1 mol) was added urea (6.0 g, 0.1 mol). After stirred at 118° C. for 4 h, the mixture was cooled to room temperature. The solidified mixture was ground to a powder, washed with n-hexane and recrystallized with ethyl acetate to afford N-methyl-N-benzylurea (12.3 g, 75% yield): mp 125°-129° C.
