Triethylamine → 6-(Chloromethyl)-2-(2,2-dimethylpropyl)-3-(2-fluoro-5-methoxyphenyl)pyridine

Participants

Reaction Steps

To a solution of (6-(2,2-dimethylpropyl)-5-(2-fluoro-5-methoxyphenyl)pyridin-2-yl)methanol (4.00 g) and triethylamine (4.00 g) in dichloromethane (20 mL) was added dropwise methanesulfonyl chloride (3.00 g) at 0° C., and the mixture was stirred at room temperature for 15 hr. Dichloromethane (150 ml) was added to the reaction mixture, and the mixture was washed with saturated brine. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (2.75 g) as a colorless oil.
