Procedure

A mixture of 3-carboxy-7-chloro-2-methylimidazo[2,1-a]isoquinoline (2.5 g) and thionyl chloride (20 ml) was refluxed for 1 hour and evaporated in vacuo. The residual solid was washed with benzene and dried in a desiccator to give 7-chloro-3-chloroformyl-2-methylimidazo[2,1-a]isoquinoline hydrochloride (2.75 g).
