25. 10 in acetonitrile. The reaction mixture was refluxed for the time given in Table 1 and monitored by GC. After completion of reaction the supported reagent was removed by filtration and solvent was evaporated. The resultant liquid is extracted with ether to yield thioamide, which was characterized by IR, GC-MS, and NMR analyses.
