Versuchsvorschrift
10.9 mg of potassium carbonate (0.08 mmol) are added to a solution of 1.67 g of (±)-2-cyclopropyl-1-methoxy-4-(trimethylsilyl)but-3-yn-2-ol (7.86 mmol) in methanol, and the mixture is stirred overnight at ambient temperature. The methanol is evaporated off and the residue is taken up with an ethyl acetate/water mixture. The product is extracted 3 times with ethyl acetate and the organic phases are then combined, dried over sodium sulphate, filtered, and concentrated under vacuum. 0.434 g of (±)-2-cyclopropyl-1-methoxybut-3-yn-2-ol is obtained in the form of an oil used without subsequent purification (crude yield=40%).
