Procedure

A solution of methyl 2-isothiocyanatobenzoate (6.0 g, prepared as described in J. Org. Chem., 1962, 27, 3701) and N,N-dimethylhydrazine (6 ml) in ethanol (60 ml) was stirred at room temperature for 1 hour. The precipitate was filtered off and dried to give methyl 2(3'-dimethylaminothioureido)benzoate (6.73 g, m.p. 149°-152°).
