Versuchsvorschrift

To a solution of methyl 3-[(1,1-dimethylprop-2-yn-1-yl)oxy]benzoate (4.0 g, 18.3 mmol) in tetrahydrofuran (10 mL) were added lithium hydroxide•monohydrate (865 mg, 20.6 mmol), methanol (10 mL) and water (5 mL), and the mixture was stirred at room temperature for 12 hr. The reaction mixture was adjusted to pH 3 by slowly adding 1N hydrochloric acid, and extracted with ethyl acetate (100 mL×2). The ethyl acetate layers were combined, and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (3.8 g, 99%) as a colorless oil.
