実験手順
Four grams (16.8 mmol) of N-(2-methoxyphenyl)-2,2,2-trifluoroacetimidoyl chloride obtained in Example 9, 1.98 g (30.2 mmol) of sodium azide, 1.16 g (8.42 mmol) of triethylamine hydrochloride, and 40 ml of toluene were introduced into a 100 ml flask and reacted at 80° C. for 14 hours. After the reaction, the reaction solution was cooled to room temperature and washed with water (30 ml×2). The organic phase was dried over anhydrous magnesium sulfate for 1 hour, filtered, and then subjected to solvent removal by evaporation. The crude product thus obtained was purified by column chromatography (silica gel, ethyl acetate:hexane=3:7), resulting in 4.01 g of 1-(2-methoxyphenyl)-5-(trifluoromethyl)-1H-tetrazole as a pale yellow oil (yield: 97.6%).
