実験手順

To a tetrahydrofuran solution (10 ml) of 4-ethylresorcinol (423 mg), sodium hydride (60% dispersion in liquid paraffin) (269 mg) was added and stirred at 0° C. for 30 minutes. Then, dibenzyl chlorophosphate (10 w/v % solution in benzene) (20 ml) was added dropwise. After stirring at room temperature for 3 hours, water (10 ml) was added to the reaction mixture, and the extraction was carried out with ethyl acetate (30 ml). Then, the extract was washed with saturated brine (10 ml), dried with anhydrous sodium sulfate and then concentrated. The residue (2.16 g) was subjected to silica gel chromatography (silica gel 60 g, chloroform to chloroform:methanol=50:1), to give 1,3-bis(dibenzylphosphonooxy)-4-ethylbenzene (1.65 g, yield: 84%) as a yellow liquid.
