Reaction Steps

3-(4-Methoxyphenyl)cyclopentanone (8.51 g) and methoxymethyltriphenylphosphonium chloride (16.9 g) were dissolved in tetrahydrofuran (200 ml). After gradually adding potassium tert-butoxide (6.70 g) while maintaining an internal temperature of 10° C. or below, the mixture was stirred at room temperature for 2.5 hours. The reaction solution was poured into water, and extraction with ethyl acetate was followed by washing with water. After drying with anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure to produce a brown oily substance which was then purified by silica gel column chromatography (n-hexane:ethyl acetate=20:1) to give 4.73 g of 1-methoxy-4-(3-methoxymethylenecyclopentyl) benzene (48.4% yield).
