To a solution of 1.8 g of 3-benzyl-2-iminobenzothiazole and a catalytic amount of dibutyltin dilaurate in 30 ml of acetone was added 0.95 g of cyclohexyl isocyanate dropwise. After seven hours, the reaction mixture was poured into approximately 100 ml of water. The crystals precipitated were collected by filtering to thereby obtain 2.0 g of the objective compound.
