Procedure

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of 2-(5-oxo-hexyl)-oxazole-4-carboxylic acid methyl ester (464 mg, 2.06 mmol) in THF (20 mL) was treated at rt with 1N NaOH (10 mL, 10 mmol) and the reaction mixture was stirred for 1 h at rt. The reaction mixture was poured in 1N HCl (20 mL) and extracted twice with EA (20 mL). The combined org. extracts were dried over MgSO4, filtered, and the solvent was removed under reduced pressure to give the title compound as a white solid. LC-MS-conditions 02: tR=0.68 min.
