Procedure

A mixture of 9-acridinecarboxylic acid hydrate (7.3 g, 30 mmole), and thionyl chloride (50 ml, 0.685 mole) was heated at reflux in a round bottom flask equipped with a reflux condenser, a drying tube, and a stirring bar. The reaction mixture was heated further for one hour after the dissolution occurred, the cooled and evaporated to remove any excess thionyl chloride. The residue was directly utilized in the subsequent reaction without further purification.
