A solution of 2,4-dimethylphenylisothiocyanate in about 70 ml. of benzene was added dropwise to an agitated solution of 3-hydroxypropylamine (3.8 grams) in about 80 ml. of benzene. The resulting reaction mixture was maintained, with stirring, at ambient temperatures for about 16 hours. Following such period, the benzene in the reaction mixture was removed in vacuo and the residual oil triturated with ethyl ether and the desired product crystallized therefrom and washed again with ethyl ether. As a result of such operations, the desired N-(2,4-dimethylphenyl)-N'-(3-hydroxypropyl)-thiourea product was obtained as a white solid having a melting point of 90° - 93°C.
