実験手順
A mixture of 2-cyano-4-hydroxymethylpyridine (0.51 g, 3.8 mmol) and thionyl chloride (0.6 ml) in toluene (20 ml) was stirred at room temperature for 1 hour. The volatiles were removed by evaporation and the residue azeotroped with toluene to give 4-chloromethyl-2-cyanopyridine hydrochloride (620 mg, 86%).
