A number of N,N-disubstituted thioformamides can be conveniently prepared in good yield by heating the corresponding secondary amine at about 110°C with commercially available dimethylthioformamide. The reaction is sensitive to steric and electronic factors as evidenced by the failure of N-methylcyclohexanamine and N-methylbenzeneamine to react. Solid thioformamides often crystallize directly from the reaction in analytically pure form.
