    Abstract: The invention relates to a process for the preparation of heteroarylcarboxylic amides and esters of formula I in which A through A , R , Hal and X one or two of the groups A , A , A , A and A represent a nitrogen atom and the other groups each independently represent CR , Hal represents a halogen atom, X represents oxygen or NR , R1 represents an optionally substituted alkyl, aryl, heteroaryl or cycloalkyl group, R represents a hydrogen atom or an alkyl group, or R and R together with the interjacent ring form a heterocyclic group, and R each independently represent a hydrogen atom or an alkyl group, which comprises: heating a mixture consisting essentially of heteroaryltrichloromethane compound of formula II, in which A through A and Hal are as hereinbefore defined, and 1.0 to 1.5 equivalents of concentrated sulfuric acid, and reacting the resulting intermediate product with an alcohol or amine of formula III HXR optionally in the presence of a diluent and/or a base.
