실험 절차

Thionyl chloride (0.75 ml, 10 mmol) was added to a solution of 4-(2-hydroxyethoxy)pyridine (0.9 g, 6.5 mmol), (J. Chem. Soc. Perkin II, 1987, 1867), in trichloromethane (20 ml) at 5° C. The mixture was stirred for 1 hour at 5° C., allowed to warm to ambient temperature and stirred for a further 2 hours. The volatiles were removed by evaporation and by azeotroping with toluene to give 4-(2-chloroethoxy)pyridine hydrochloride (1.3 g, 100%).
