A mixture of 2-(4-Methoxy-benzyl)-oxazole-4-carboxylic acid methyl ester (40 mg, 0.16 mmol), methanol (2 mL) and 1N NaOH (1 mL) was heated at 60° C. for 2 hours and allowed to stand at 25° C. for 30 minutes. After dilution with water, the mixture was adjusted to pH 2 with 2N HCl and extracted with ether. The organic layers were combined, dried with MgSO4 and evaporated to dryness to yield 25 mg (66%) of 2-(4-Methoxy-benzyl)-oxazole-4-carboxylic acid as a white solid. ESI-MS m/z calc. 233.2, found 234.2 (M+1)+. Retention time of 2.27 minutes.
