Versuchsvorschrift
To a suspension of sodium hydride (0.170 g, 4.24 mmol) in tetrahydrofuran (10 mL) was added phenylmethanethiol (0.338 ml, 2.88 mmol) dropwise at 0° C. The reaction mixture was stirred at 0° C. for 15 minutes then 2-fluoro-6-(trifluoromethyl)pyridine (0.365 ml, 3.03 mmol) was added dropwise. The reaction mixture was stirred at 0° C. for 30 minutes. Methanol (1 mL) was added carefully and the reaction mixture was stirred at 0° C. for a further 10 minutes then water (5 mL) and dichloromethane (10 mL) were added. The organic layer was recovered using a phase separator cartridge then concentrated in vacuo to give 2-(benzylthio)-6-(trifluoromethyl)pyridine (538 mg) as a colourless oil. LCMS (Method F, ES-API): RT 2.80 min, m+H=270.1.
