Reaction Steps

Triphenylphosphine (0.461 g, 1.758 mmol) is added to a mixture of 3-bromo-5-hydroxy pyridine (0.3 g, 1.724 mmol) in THF (10 ml). Ethanol (0.103 ml) is added the reaction mixture is cooled to 0° C. (ice-bath). DEAD (0.277 ml, 1.758 mmol) is finally added and the mixture is warmed to room temperature and stirred overnight. The crude material is purified by flash chromatography by wet loading onto a 50 g silica column eluting with 3:1 iso-hexanes:EtOAc to afford the title compound as a yellow oil, [MH+ 201.88].
