실험 절차
N-(3-Chloro-4-fluorophenyl)-4-(3-morpholin-4-ylpropyl)-1,2,5-oxadiazole-3-carboxamide (10.0 mg, 27.1 μmol) was suspended in benzene (0.4 mL) under a nitrogen atmosphere and phosphorus pentachloride (6.2 mg, 29.8 μmol) was added and the solution was heated at reflux for 2.5 h. The reaction was then stripped to dryness in vacuo. The reaction was dissolved in EtOH (0.3 mL) and hydroxylamine (40 μL, 0.7 mmol) (50% solution in water) was added to the reaction. After stirring for 1 h, the reaction solution was diluted with MeOH and purified with preparative LCMS to give product (5.2 mg, 50%). LCMS for C16H20ClFN5O3(M+H)+: m/z=384.1.
