실험 절차

The mixture of 4.79 g of 4-amino-2-chloro-6,7-dimethoxyquinazoline, 4.49 g of 4,4-dimethyl-1-(4-piperidinyl)-piperidin-2,6-dione, 4.24 g of anhydrous sodium carbonate and 75 ml of dimethylformamide is stirred at 150° under nitrogen for 6 hours. It is filtered, the filtrate evaporated, the residue dissolved in ethyl acetate and the solution washed with aqueous sodium carbonate and water. It is dried, evaporated, the residue triturated with isopropanol, filtered off and discarded. The filtrate is made strongly acidic with hydrogen chloride, the precipitate filtered off and triturated with 175 ml of boiling methanol, to yield the 1-[1-(4-amino-6,7-dimethoxy-2-quinazolinyl)-4-piperidinyl]-4,4-dimethyl-piperidin-2,6-dione monohydrochloride, melting at 279°-280° with decomposition.
