実験手順
To a mixture of 6-hydrazinyl-3-phenylpyrido[2,3-b]pyrazin-2(1H)-one (3-3) (300 mg, 1.19 mmol), HOBt (218 mg, 1.42 mmol) and oxamic acid (130 mg, 1.42 mmol) in NMP (12 mL) was added EDC (272 mg, 1.42 mmol) at room temperature and the mixture was stirred for 30 min. After addition of TFA (0.091 mL, 1.19 mmol), the mixture was heated under microwave irradiation at 150° C. for 30 minutes. To a mixture was added water (60 mL) and the precipitate was collected by filtration to give 3-hydroxy-2-phenyl[1,2,4]triazolo[4′,3′:1,6]pyrido[2,3-b]pyrazin-9-carboxamide (9-1) as a yellow powder.
