Ethyl 5-(3,3-dimethylbut-1-yn-1-yl)-4-methylisoxazole-3-carboxylate (101 mg, 0.429 mmol) in THF (3 mL) and MeOH (1.800 mL) was treated at room temperature with 2M NaOH (aq) (0.429 mL, 0.859 mmol) for 1 hour. 2M HCl (aq) (0.6 mL) and water were added and the aqueous was extracted with EtOAc. The combined organic extracts were dried over MgSO4 and filtered. The solvent was removed under reduced pressure to afford the title compound;
