Reaction Conditions

Reaction Steps

Potassium carbonate (11.3 g, 81.5 mmol) and benzyl chloride (9.5 mL, 82.6 mmol) were added to a solution of 4-(2-ethoxyethoxy)-3-hydroxybenzaldehyde described in Production Example 24-1 (13.2 g, 62.7 mmol) in ethanol (130 mL) under nitrogen atmosphere at room temperature. The liquid mixture was stirred under a thermal condition of 90° C. for 2 hours. The reaction liquid was cooled to 0° C. and then diluted with 2 M hydrochloric acid, ethyl acetate, and water. The organic layer was washed with a saturated saline solution and then dried over anhydrous magnesium sulfate. The drying agent was separated by filtration and the filtrate was concentrated under vacuum. The resultant residue was dissolved in dichloromethane and the resultant was purified with silica gel column chromatography (n-heptane:ethyl acetate=9:1-1:1) to obtain the title compound (13.5 g, 72%).
