Reaction Steps

Thionyl chloride (10 ml) was slowly added to a solution of 6-phenyl-3-pyridylmethanol (11.60 g) in toluene (100 ml) at room temperature, which was stirred at 100° C. for 1 hour. After cooling, the reaction mixture was poured into saturated aqueous sodium bicarbonate solution, which was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4) and concentrated to obtain 5-chloromethyl-2-phenylpyridine (11.49 g, yield 89%) as colorless crystals. This was recrystallized from ethyl acetate-hexane. Melting point: 95–96° C.
