实验步骤: Under a nitrogen atmosphere, 3.83 g of a 45% aqueous sodium hydroxide solution, 120 mg of tetrabutylammonium bromide and 5 ml of toluene were mixed, and to the resulting mixture solution, a solution of 1.0 g of 2-ethyl-2-methylbutanol and 1.51 g of 6-phenoxy-2-chloromethylpyridine in 5 ml of toluene was added at room temperature. After stirring at room temperature for 16 hours, the reaction solution was poured into dilute hydrochloric acid-ice water and extracted twice with toluene. The toluene 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, n-hexane: ethyl acetate=50:1) to obtain 1.48 g of desired 6-phenoxy-2-pyridylmethyl 2-ethyl-2-methylbutyl ether [present compound (35)] as a colorless oily product. extracted twice with toluene washed with a saturated aqueous sodium chloride solution dried over anhydrous magnesium sulfate the solvent was removed under reduced pressure
