Abstract
Abstract The present invention concerns novel compounds of the formula, WHEREIN R1 is hydrogen, halogen, or alkoxy of one to four carbon atoms, R2 is alkyl of one to four carbon atoms, and -A-B- is -CO-CH2-CO- or -CO-CH2-, and pharmaceutically acceptable acid addition salts thereof. The compounds are histaminolytics. Compounds wherein -A-B- is CO-CH2- are antaminics, i.e. aside from histaminolytic properties, they possess serotonin - antagonistic and anticholinergic properties.
