Following the procedure described in Example 1, 2-(phenylthio)benzoyl chloride is prepared from 0.065 mole of 2-(phenylthio)benzoic acid and excess thionyl chloride. A solution of the oily acid chloride in 50 ml. of benzene is added dropwise with stirring to a solution of 7 g. of dimethylamine in 50 ml. of benzene. The mixture is heated briefly to refluxing. Evaporation of the solvent under reduced pressure leaves N,N-dimethyl-2-(phenylthio)benzamide as the residue.
