The reaction of methanetricarboxylates 1a,b with 2‐aminopyridine, 2‐aminopyrimidine, 2‐aminothiazole as well as 2‐aminobenzothiazole yields corresponding heteroarylcarboxylic acid esters 2a,b , 5 , 8 , 11a,b . These heterocyclic esters were used as a starting material by the reaction with primary amines to obtaining a number of heteroarylcarboxylic amides 4a‐j , 6 , 10a,b , 13a‐g bearing various substituents on the carboxamide group.
