Versuchsvorschrift
(6-Trifluoromethylpyridin-2-yl)methanol (760 mg, 4.3 mmol) was dissolved in CH2Cl2 and thionyl chloride was added slowly at room temperature. The reaction mixture was stirred at room temperature for 4 h. Solvent was removed under the reduced pressure, the pH was adjusted to 5, and the product was extracted with EtOAc. Purification by flash column (5% EtOAc-Hexane) gave 2-chloromethyl-6-trifluoromethylpyridine (200 mg) as a white solid.
