A suspension of 1-(4-methoxycarbonylphenyl)-4-(4-n-pentyloxyphenyl) butane-1,4-dione (765 mg) and phosphorus pentasulfide (533 mg) in tetrahydrofuran (10 ml) was stirred for 6 hours at room temperature, poured into water and stirred for 1 hour. The precipitate was collected by filtration, washed with water and dried under reduced pressure to give methyl 4-[5-(4-n-pentyloxyphenyl)thiophen-2-yl]benzoate (668 mg).
