Procedure

Methoxymethyl chloride (8.4 mL) and potassium carbonate (30 g) were added to an N,N-dimethylformamide (150 mL) solution of 3-propylphenol (10 g) at room temperature, followed by stirring at 50° C. for one day. The reaction solution was poured into ice water. The insoluble matter was filtered off, and extracted with a hexane-ethyl acetate (1:1) mixed solvent. The organic layer was successively washed with water and brine. The resultant was dried over magnesium sulfate, and concentrated. The obtained residue was purified by silica gel column chromatography (hexane only to hexane:ethyl acetate=10:1), to thereby obtain the title compound (8.0 g) having the following physical properties.
