실험 절차

A mixture of 4-amino-2-methylmercapto-6,7-dimethoxyquinazoline (0.1 mole) and from 0.1 to 0.15 mole of N-(cyclopentylcarbonyl)piperazine in 150 ml. of isoamyl alcohol is refluxed for a period of 8 to 24 hours. The solvent is evaporated and residual material, treated according to procedure of Example 127(a), provides 4-amino-2-[4-(cyclopentylcarbonyl)-1-piperazinyl]-6,7-dimethoxyquinazoline.
