実験手順

In a sealed tube, N-(2-methoxyethyl)methylamine (3 ml) and water (3 ml) were added to 4-[3-bromo-5-(6-phenylpyridin-3-yl)-4H-1,2,4-triazol-4-yl]-2,1,3-benzooxadiazol (336 mg) prepared in the Production Example 5, and stirred at 160° C. for 6 hours. After the reaction solution was cooled to ambient temperature, chloroform was added to the solution, which was then washed with saturated aqueous sodium hydrogen carbonate solution. The organic layer was dried over anhydrous magnesium sulfate. After the solvent was evaporated under reduced pressure, the resulting solid was recrystallized from ethyl acetate, to afford the entitled compound as white crystal (66 mg, 19%). The physico-chemical values are as follows.
