実験手順
5-hydroxymethyl-2-methylthiopyrimidine (0.1 g, 0.61 mmol), triphenylphosphine (0.45 g, 1.7 mmol) and carbon tetrabromide (0.28 g, 0.85 mmol) are stirred in benzene (5 mL) for 24 h. The mixture is evaporated and the residue is purified by flash chromatography (silica gel, 4:1 hexanes/ethyl acetate) to provide the intermediate title compound as a white solid (0.08 g, 61%). MS (ES), 219/221 [M+H]+ (Br).
