## Abstract An improved protocol for the synthesis of __N__‐substituted pyridine‐2‐thiocarboxamides under the conditions of the Willgerodt−Kindler reaction, employing a catalytic amount of sodium sulfide nonahydrate, has been developed. Following this protocol, eight thioamides carrying aromatic or
