    摘要: New quinazolines are described of general formula (I), in which Ar is an unsubstituted phenyl group or a phenyl group mono-substituted with a methoxy, ethoxy or methyl group; an unsubstituted pyridyl group (2-, 3- or 4-yl) or a pyridyl group mono-substituted with a methoxy or methyl group; an unsubstituted furyl group (2- or 3-yl) or a furyl group substituted with a methoxy or methyl group; a benzofuryl group (2- or 3-yl); an indolyl group (2- or 3-yl); a thiophenyl group (2- or 3-yl); a naphthyl group (1- or 2-yl) and their salts obtained from pharmaceutically acceptable inorganic or organic acids. These new quinazolines are useful in the treatment of hypertension, congestive heart failure, prostate hypertrophy, various urinary tract disorders and pathological symptoms caused by hyperactivity or disfunctioning of the noradrenergic neural system. ##STR1##
