Procedure

Diethyl (E)-2-(4-pyridyl)ethenylphosphonate (10.3 g, 42 mmol) was dissolved in ethanol (25 ml), and 10% palladium-carbon (1.0 g) was added thereto. The mixture was stirred under hydrogen atmosphere at room temperature for 5 hrs. Palladium-carbon was filtered off, and the filtrate was concentrated to give the titled compound (10.3 g, 100%).
