Procedure

2-(2-Pyridyl)ethanesulfonic acid (1.00 g) was suspended in thionyl chloride (5 ml). Catalytic amount of DMF was added to the suspension. The mixture was stirred at 50° C. for 30 minutes, and was concentrated in vacuo. The resulting solid was recovered and washed with Et2O to give 1.41 g of 2-(2-pyridyl)ethanesulfonyl chloride hydrochloride as a solid.
