✦ Synopsis
CIQuinoline and [3-Clquinoline were synthesised by a five-step process starting from isatin.
Acetylation of isatin with acetyl chloride labelled in either the 1or 2-position, was followed by the Pfitzinger reaction to give 2-hydroxy-4-quinoline carboxylic acid labelled in the 2- or 3-position.
Decarboxylation by pyrolysis was followed by chlorination and reduction to the labelled quinolines.
The overall yield was approximately 20%
