2-aminomethyl-5-chlorobenzhydrol (10 g; 0.04 mole) in 100 ml methanol and 2 ml triethylamine was treated dropwise with a solution of phenethyl isothiocyanate (8.6 g; 0.053 mole) in 25 ml of methanol. After 16 hours at room temperature the reaction mixture was evaporated and the residue was extracted with petroleum ether. The residual oil was recrystallized from diisopropyl ether to yield 1-(4-chloro-2-(α-hydroxybenzyl)benzyl)-3-phenethylthiourea as a white powder (M.Pt. 97° -- 101° ).
