Procedure
Thionyl chloride (2.2 ml, 30 mmol) was added slowly to a solution of 4-(3-hydroxypropoxy)pyridine (3.1 g, 20 mmol) in trichloromethane (40 ml) at 5° C. The mixture was stirred at 5° C. for 1 hour and then at ambient temperature for 2 hours. The volatiles were removed by evaporation, the residue azeotroped with toluene and dried under vacuum to give 4-(3-chloropropoxy)pyridine hydrochloride (3.81 g, 91%) as a solid.
