Reaction Steps
A solution of 6-methoxymethyl-2-pyridinemethanol (860 mg, 5.64 mmol) and triphenylphosphine (1.78 g, 6.77 mmol) in dichloromethane (40 mL) at 0° C. was treated portion wise with CBr4 (2.80 g, 8.43 mmol), stirred for 1 h, concentrated in vacuo and purified by chromatography [SiO2; isohexane:EtOAc (3:1)] to give the title compound (1.20 g, 99%) as a colourless oil; NMR δH (400 MHz, CDCl3) 7.71 (1H, t, J 8.0 Hz), 7.35 (2H, d, J 8.0 Hz), 4.58 (2H, s) and 4.54 (2H, s).
