실험 절차

Under a nitrogen atmosphere, 0.65 g of sodium hydride (60% oily suspension) was suspended in 10 ml of dry DMF, and a solution of 3.23 g of 2-chloromethyl-6-phenoxypyridine and 2.00 g of 3-chloro-2,2-dimethylpropanol in 10 ml of dry DMF was added dropwise with ice-cooling. After stirring for 12 hours at room temperature, the reaction solution was poured into dilute hydrochloric acid-ice water and extracted twice with diethyl ether. The ether layers were combined, washed with a saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was subjected to column chromatography on silica gel (developing solvent, hexane:ethyl acetate=50:1) to obtain 0.52 g of desired 6-phenoxy-2-pyridylmethyl 3-chloro-2,2-dimethylpropyl ether [present compound (1)] as a colorless oily product.
