실험 절차
A mixture of methyl 4-hydroxymethyl-2-nitrobenzoate (1.49 g), thionyl chloride (1.08 g), dry pyridine (0.1 g), dry ether (70 ml) and dry tetrahydrofuran (20 ml) was stirred overnight. The reaction mixture was washed in turn with 1N hydrochloric acid and sat. sodium bicarbonate solution, dried over magnesium sulfate and evaporated to give methyl 4-chloromethyl-2-nitrobenzoate (1.60 g).
