Reaction Steps

Methyl 2-(4-hydroxybut-1-yn-1-yl)-3-(methyloxy)benzoate (0.056 g, 0.24 mmol) was dissolved in methanol (2 ml), and a solution of potassium hydroxide (0.027 g, 0.48 mmol) in water (0.5 ml) was added. The reaction mixture was stirred at 60° C. for 1 h, cooled to room temperature, and 1.5M hydrochloric acid was added to pH 4. The aqueous mixture was extracted with ethyl acetate, and the organic layer was washed with brine then dried over sodium sulfate. The mixture was then filtered and concentrated to give 2-(4-hydroxybut-1-yn-1-yl)-3-(methyloxy)benzoic acid (0.052 g, 99% yield). MS (EI) for C12H12O4: 219 (M−H).
