反応手順
1.0 g (2.6 mmol) of ethyl 8-iodo-1-methyl-4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline-3-carboxylate were dissolved in a mixture of 100 mL of methanol and 100 mL of ammonium hydrate 33%. The solution was stirred in a close bottle at 60° C. for 4 hours. The resulting precipitate was collected giving 0.5 g (54% yield) of the title compound.
