To a solution of 16.3 grams benzoyl isothiocyanate, prepared by refluxing 13.6 grams of dried sodium isothiocyanate with 17 grams of benzoyl chloride in 30 ml. of benzene, is slowly added, at room temperature, 28 grams of N-isopropyl-N-(3,4-methylenedioxyphenyl)-amine (prepared as in Example A) in 150 ml. benzene. The reaction mixture is stirred for 30 minutes at 20°C. and a solid forms which is recrystallized from benzene to yield N-isopropyl-N-(3,4-methylenedioxyphenyl)-N'-benzoyl thiourea melting at 152°-154°C.
