Methyl iodide → 2-Chloro-5-(methoxymethyl)pyridine

참여 물질

반응 단계

2.6 g (23.0 mmol) potassium tert-butylate are dissolved in 50 ml THF. 3.0 g (20.9 mmol) (6-chloropyridin-3-yl)methanol are added and the mixture is stirred at RT for 15 min. 4.4 g (31.3 mmol) iodomethane are then added and the mixture is stirred for approx. 30 min until the slightly exothermic reaction has subsided. The solvent is removed, the residue is taken up in methylene chloride and the mixture is washed twice with water. The mixture is dried over magnesium sulfate and concentrated and the residue is purified by column chromatography over silica gel (Biotage chromatography, mobile phase: cyclohexane/ethyl acetate 85:15).
