use of phosphoruspentasulfide as a thiontion agent were developed. The first method was based on the reaction of cyanopyridine with phosphoruspentasulfide in alcoholic ammonium solution followed by hydrolysis. The method provided the corresponding thioamides in 60–90% yield. The second procedure included the reaction of phosphoruspentasulfide with 4-cyanopyridine in aqueous ammonia solution, which
