실험 절차

To a solution of [4-(5-Amino-[1,3,4]oxadiazol-2-yl)-pyridin-3-yl]-(2-floro-4-iodo-phenyl)-amine (150 mg, 0.38 mmol) in ethanol (10 mL) KOH 9212 mg, 3.78 mmol) was added. The reaction mixture was refluxed for 3 hrs. Then, added acetic acid was added to bring the pH to 5. The volatives were stripped and the residue was dissolved in EtOAc, and washed with 5% Na2CO3, and brine, and then dried over anhydrous MgSO4. After filtration and solvent removal the remaining crude product was subjected to silica gel column chromatography (eluent:Hex:ane EtOAc=1:1) to afford the desired product (45 mg). [5.08 min; 394(M+1)]
