Procedure
106.8 g (0.65 mol) of 5-methyl-2,3-pyridine dicarboxylic acid anhydride were dissolved in 427 g chlorobenzene and heated up to 85° C. A solution of 0.64 g (0.004 mol) AIBN in 99.0 g (0.66 mol) SO2Cl2 was added during 45 min. The mixture was stirred for additional 90 min at 85° C. Chlorobenzene was partly distilled off and the solution was cooled to 10° C. via 10 h ramp. The precipitate was filtered off and washed with chlorobenzene/hexane.
