実験手順

To a solution of 2-cyclopropyl-N-methoxy-N-methyloxazole-4-carboxamide (0.102 g, 0.52 mmol) in dry dichloromethane (15 mL) was added diisobutylaluminum hydride (1M in toluene) (1.04 ml, 1.04 mmol) at −78° C. The reaction mixture was stirred at −78° C. for 45 minutes. The reaction mixture was quenched with aqueous sodium hydroxide (2M) and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrated under reduced pressure to afford 2-cyclopropyloxazole-4-carbaldehyde which was used without further purification. (65 mg) MS (API-ES+) (M+H) 138.2.
