実験手順
Into a round bottom flask was added 7-amino-2-methylpyrazolo[1,5-a]pyrimidine-6-carbaldehyde (1-2) (5.30 g, 30 mmol), methy phenylacetate (18.0 g, 120 mmol), potassium tert-butoxide (5.80 g, 60 mmol), and toluene (100 mL). The reaction mixture was heated to 105° C. while stirring under an atmosphere of nitrogen for 30 min. Then DMF (100 mL) was added and the mixture was stirred at 100° C. for 3 days. The reaction mixture was cooled to room temperature and concentrated in vacuo. The resulting residue was dissolved in DCM (600 mL) and then water (400 mL) was added to the solution. The precipitated solid was collected by filtration and the solid was washed with water (50 mL) and DCM (100 mL). The solid was dried over an oil pump for 2 days to give 2-methyl-7-phenylpyrazolo[1,5-a]pyrido[3,2-e]pyrimidin-8(9H)-one (1-3) as a yellow solid.
