Procedure

To a solution of 3-hydroxy-isoxazole-5-carboxylic acid methyl ester (286 mg, 2.0 mmol) in methanol (7 mL) is added 1N NaOH (4.0 mL, 4.0 mmol) and the mixture is stirred at room temperature for 18 hrs. The solvent is removed under reduced pressure and 4.0 mL of 1N HCl is added to the residue. The resulting solution is lyophilized to give the product which is used as is in subsequent reactions.
