Procedure

To a 35° C. magnetically stirred solution of 2.40 g (11.8 mmol., 1.00 equivalent) of 2-(p-chlorophenyl)pyrrole-3-carbonitrile, and 65 mL of glacial acetic acid is added dropwise by syringe 0.75 mL (1.26 g, 9.34 mmol., 0.79 equivalent) of sulfuryl chloride over a period of 5 minutes. Approximately 5 minutes after the completion of the addition, a solid precipitated out of the reaction solution. After stirring at room temperature for 45 minutes, the reaction mixture is filtered and the collected solid is washed well with cold acetic acid to give 2.08 g (74% crude yield) of an off-white solid. This solid is recrystallized from 75 mL of hot acetic acid to give 1.63 g (58% yield) of 97 wt % pure. Product mp 258.5°-261° C.
