Potassium Fluoride → 2-(5-Fluoropyridin-2-yl)but-3-yn-2-ol

Participants

Reaction Steps

A solution of 2-(5-fluoropyridin-2-yl)-4-(trimethylsilyl)but-3-yn-2-ol (1 g, 4.21 mmol) and potassium fluoride (987 mg, 16.99 mmol) in methanol (10 mL) was stirred for 2 hr at 50° C. The resulting solution was diluted with ethyl acetate (20 mL) and the solid material was removed by filtration. The filtrate was concentrated in vacuo to give 600 mg (86%) of the title compound as yellow oil: LC-MS: m/z=+166 (M+H)+.
