To a mixture of 5-benzyloxy-4-methoxy-2-(5-methyl-[1,2,4]oxadiazol-3-yl)benzaldehyde (reference example 15-1) (450 mg) and tetrahydrofuran (5.6 mL) was added dropwise phenylmagnesium bromide (1.08 mol/L tetrahydrofuran solution, 1.4 mL) in an ice salt bath. After stirring at the same temperature for 30 minutes, an aqueous solution of ammonium chloride, 2 mol/L hydrochloric acid and ethyl acetate were added to the mixture. The separated organic layer was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the title compound (564 mg).
