실험 절차

To a mixture of 10 ml of anhydrous N,N-dimethylformamide and 72 mg of sodium hydride (60% oil dispersion) was added dropwise an anhydrous N,N-dimethyl-formamide (5 ml) solution of 300 mg of 4-(1-pyrazolyl)methylphenol under stirring over 10 minutes. After stirring at room temperature for 1 hour, the mixture was cooled to 5° to 10° C., to which an anhydrous N,N-dimethylformamide (5 ml) solution of 505 mg of 2-(2-pyridyloxy)ethyl p-toluenesulfonate was added dropwise over 30 minutes. The mixture was stirred at room temperature overnight and then at 60° to 70° C. for further 2 hours. The reaction mixture was poured into 50 ml of ice water, which was extracted twice with 30 ml of ethyl acetate. The organic layers were combined, washed with water, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, which afforded 208 mg of 4-(1-pyrazolyl)methylphenyl 2-(2-pyridyloxy)ethyl ether (compound 1). Yield, 41%.
