反应详情

A mixture of methyl 3-(5-phenyl-1,3,4-oxadiazol-2-yl)propanoate (600 mg, 2.0 mmol) in 1 M of aqueous NaOH (10 mL) and Methanol (10 mL) was stirred at room temperature overnight. The reaction solution was adjusted to pH 5 and extracted with ethyl acetate three times. The combined organic layers were dried, filtered and concentrated to yield the desired product (0.50 g, 83%). LCMS calculated for C11H11N2O3 (M+H): 219.1. Found 219.1.
