Reaction Steps

The 3,4-dimethylphenyl(thioacetamide) was prepared by passing a slow stream of hydrogen sulphide through a solution of 3,4-dimethylphenylacetonitrile (56.6 g.) in pyridine (60 ml.) and triethylamine (39.4 g.) during 12 hours. The reaction mixture was evaporated under reduced pressure and the residue was recrystallised from a mixture of benzene and light petroleum (b.p. 60°-80°) to give 3,4-dimethylphenyl (thioacetamide), m.p. 91°-94°.
