Reaction Steps

In a 20-mL sealed tube, a suspension of 2-(1H-pyrazol-4-yl)-4-(trimethylsilyl)but-3-yn-2-ol (1.4 g, 6.72 mmol, 1.00 equiv) and potassium fluoride dihydrate (2.0 g) in methanol (10 mL) was stirred for 1.5 h at 50° C. The resulting mixture was concentrated under vacuum. The resulting solution was diluted with 20 mL of water. The resulting solution was extracted with 3×20 mL of tetrahydrofuran/ethyl acetate (2/1) and the organic layers combined and dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted in 1 g (98%) of 2-(1H-pyrazol-4-yl)but-3-yn-2-ol as a solid.
