Procedure

To an ethanol solution (10 ml) of 1,3-bis(dibenzylphosphonooxy)-4-isopropylbenzene (1.01 g), 5% palladium-carbon (50% water-containing product) (109 mg) was added and stirred under a hydrogen atmosphere at room temperature for 14 hours. After the removal of the catalyst by filtration, the filtrate was concentrated, to give the title compound (464 mg, yield: 100%) as a yellow paste.
