To an ethanol solution (10 ml) of 1,3-bis(dibenzylphosphonooxy)-4-ethylbenzene (1.09 g), 5% palladium-carbon (50% water-containing product) (97.3 mg) was added and stirred under a hydrogen atmosphere at room temperature for 7 hours. After the removal of the catalyst by filtration, the filtrate was concentrated, to give the title compound (463 mg, yield: 93%) as a pale yellow solid.
