Reaction Steps

To a solution of 2-methoxy-5-(trifluoromethyl)pyridin-3-yl)methanol (14) (0.4 g, 1.93 mmol) dissolved in DCM was added thionyl chloride (0.38 ml, 3.86 mmol). The reaction mixture was stirred for 2 h at RT. The solvent was evaporated under the reduced pressure and the reaction mixture was poured in to water (50 mL) and extracted with DCM (2×50 mL). The combined organic layer was washed with water, brine, dried over sodium sulfate, and concentrated at reduced pressure to yield 3-(chloromethyl)-2-methoxy-5-(trifluoromethyl)pyridine (15) as a liquid. (Yield 0.3 g, 69.76%)
