実験手順

A solution of 5-ethyl-2-phenyl-oxazole-4-carboxylic acid benzyl ester (1 g, 3.25 mmol) in 30 mL of ethanol was hydrogenated at 30 psi with 10% Pd/C (200 mg) at room temperature for two hours. The reaction mixture was filtered through a celite plug, evaporated and placed under high vacuum to give 5-ethyl-2-phenyl-oxazole-4-carboxylic acid, that was used without further purification. LCMS calcd for C12H11NO3 (m/e) 217, obsd 218 (M+H).
