実験手順

A solution of 120 mg of 1,4-dihydroxythioxanthone in 100 ml of acetone is stirred for 0.5 h at room temperature with 138 mg of potassium carbonate. A solution of 80 mg of 1-bromo-2-chloroethane in 5 ml of acetone is then added and the mixture refluxed for 24 h. The heterogeneous mixture is cooled, filtered, concentrated under reduced pressure and purified by silica gel column chromatography using a 1:1 mixture of hexanes and ethyl acetate to produce 100 mg of a yellow-red crystals (65%).
