Reaction Steps
21.4 g (0.1 mole) of 1-nitropyrazolo[1,5-c]quinazoline are treated with hydrogen in ethanol and in the presence of palladium/carbon at room temperature and atmospheric pressure. When the hydrogen consumption ceases, the solution is filtered and evaporated. 14.7 g (80%) of 1-aminopyrazolo[1,5-c]quinazoline are obtained. M.p.: 168°-170° C.
