To 20 g. (0.12 mole) of 2,4-dimethylphenylisothiocyanate in 30 ml. of acetone was added dropwise 10 g. (0.16 mole) of ethanolamine in 20 ml. acetone. The solution was refluxed 1 hour then cooled to 4° C., to give crystals which were filtered off, washed with cold ethanol and dried to afford 1-(2,4-dimethylphenyl)-3-(2-hydroxyethyl)-thiourea, 16.8 g. (54% yield) of white crystals m.p. 137.5°-139° C.
