Reaction Steps
To a solution of 4-pyridylcarbinol (3 g, 27.5 mmol) in 30 mL of CHCl3 was added phosphorus pentabromide (5.93 g, 13.7 mmol). The solution was refluxed for 1 hour. The solvent was removed in vacuo and recrystallized in ethanol to afford the title compound as a white solid (4.05 g, 58.1%). ES (+) MS m/e=173 (M+H).
