ABSTRACT:
Novel triazoloquinazolones of the formula ##STR1## wherein R and R' are individually selected from the group consisting of hydrogen, halogen, nitro and alkyl and alkoxy of 1 to 3 carbon atoms, Y is selected from the group consisting of alkyl of 1 to 6 carbon atoms, alkenyl of 2 to 4 carbon atoms, cycloalkyl of 3 to 8 carbon atoms, aryl of 6 to 8 carbon atoms and aralkyl of 7 to 8 carbon atoms, B is an alkylene of 1 to 3 carbon atoms, X is selected from the group consisting of ##STR2## R.sub.1 and R.sub.2 are individually selected from the group consisting of hydrogen, alkyl of 1 to 6 carbon atoms, cycloalkyl of 3 to 8 carbon atoms, aryl of 6 to 8 carbon atoms, aralkyl of 7 to 8 carbon atoms, aminoalkyl of 2 to 4 carbon atoms, mono- and dialkylaminoalkyl with each alkyl having 2 to 4 carbon atoms, piperidinoalkyl of 1 to 4 alkyl carbon atoms, morpholinoalkyl of 1 to 4 alkyl carbon atoms and piperazinylalkyl of 1 to 4 alkyl carbon atoms or R.sub.1 and R.sub.2 taken together with the nitrogen to which they are attached form a saturated mono- or bicyclic heterocyclic ring with 4 to 8 carbon atoms optionally substituted with 1 to 2 methyls and optionally containing in the ring a heteroatom selected from --O--, --S-- and ##STR3## and R.sub.3 is selected from the group consisting of hydrogen, alkyl of 1 to 3 carbon atoms, hydroxyalkyl of 1 to 3 carbon atoms, alkoxycarbonyl of 2 to 5 carbon atoms, aryl of 6 to 8 carbon atoms and aralkyl of 7 to 8 carbon atoms and their non-toxic, pharmaceutically acceptable acid addition salts having antihistaminic and bronchospasmolytic activity and their preparation and intermediates.
