A series of quinazolines, with cardiovascular activity, having 2,3-dihydroxypropoxy or 2-hydroxy-3-t- butylaminopropoxy groups substituted at the 4-position and chlorine or 2-aroylpiperazinyl groups at the 2-position have been synthesized. The introduction of the alkoxy substituent at C-4 was carried out under phase-transfer catalysis conditions.
合成了一系列具有心血管活性的喹唑啉,它们具有在4-位被取代的2,3-二羟基丙氧基或2-羟基-3-叔丁基氨基丙氧基和在2-位具有氯或2-芳酰基哌嗪基的基团。在相转移催化条件下在C-4处引入烷氧基取代基。
