실험 절차
4-Chloro-6,7-dimethoxy quinazoline (1.1 g.), 4- (2-methanesulphonamidoethyl)piperidine hydrochloride (1.5 g.) and triethylamine (1.5 ml.) in ethanol (30 ml.) were heated together under reflux for 1.5 hours. The solution was then cooled to room temperature, concentrated in vacuo, suspended in water (70 ml.) and basified to pH 10 with 10% aqueous sodium carbonate solution. The mixture was extracted with chloroform (2×70 ml.), the extracts combined, dried (MgSO4), and taken to dryness in vacuo. The resultant pale yellow oil was triturated with ether (70 ml.) to give a white solid which was collected by filtration. Crystallization of this solid from ethanol yielded 6,7-dimethoxy-4-[4-(2-methanesulphonamidoethyl)-piperidino]quinazoline (1.7 g.), m.p. 162°-164° C.
