実験手順

To a solution of tert-butyl 4-({3-[(2,6-diethylphenyl)carbamoyl]-1-methyl-4,5-dihydro-1H-pyrazolo[4,3-h]quinazolin-8-yl}amino)-3-methoxybenzoate (500 mg, 0.857 mmol) in dimethylformamide (8 mL), trifluoro acetic acid (0.600 mL), were added. The mixture was stirred at room temperature overnight. Water was added and the mixture extracted with ethylacetate. The organic solvent evaporated to dryness. To give 450 mg of the title compound in quantitative yield.
