Reaction Steps

5-(1-Methylethoxy)picolinaldehyde (24 mg, 0.145 mmol) was dissolved in tetrahydrofuran (1.5 mL), added methylmagnesium bromide (230 μL, 0.218 mmol) under ice-cold conditions, and the mixture was stirred at 0° C. for 0.5 hours. The mixture was further stirred at room temperature for 0.5 hours. The reaction solution was added 1N aqueous solution of hydrochloric acid and an aqueous solution of sodium hydrogen carbonate, and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (hexane/ethyl acetate), and 1-[5-(1-methylethoxy)pyridin-2-yl]ethanol (27 mg (yield 98%)) was obtained as a brown oil.
