Procedure

Chlorosulfonic acid (3.0 ml, 0.0454 mol, 150 M %) was added slowly to a solution of dry pyridine (9.84 ml, 0.121 mol) in dry dimethylformamide (60 ml) which had been cooled to -10°. The resulting clear solution was stirred for 10 minutes at room temperature.

Workup

  1. temperaturehad been cooled to -10°
