4-Fluoro-3-methoxymethoxy-5-phenylisoxazole (0.44 g) was dissolved in a solution of 4N hydrochloric acid/dioxane (5.0 ml), and the solution was stirred at room temperature for one hour. After the reaction, the solvent was evaporated under reduced pressure and the crystal thus obtained was washed with dichloromethane (10 ml) to obtain the title compound (0.30 g, 83%) as colorless crystals.
