Abstract
These are described compounds of formula (I) ##STR1## or an acid addition salt thereof; in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently represent hydrogen, C.sub.1-4 alkyl, C.sub.2-4 alkenyl, halogen, C.sub.1-4 haloalkyl, nitro, C.sub.1-4 alkoxy, C.sub.1-4 haloalkoxy, C.sub.1-4 alkylthio or phenylsulphonyl; in which R.sup.5 is a group of the formula ##STR2## where R.sup.7 is hydrogen or C.sub.1-6 alkyl, R.sup.8 is hydrogen or C.sub.1-4 alkyl and n is 0 or 1, provided that when R.sup.7 is hydrogen n is 0; and in which R.sup.6 is attached to the 1, 2 or 3 position of the triazole ring and is hydrogen, C.sub.1-10 alkyl, C.sub.3-7 cycloalkyl, C.sub.3-7 cycloalkyl C.sub.1-4 alkyl, phenyl, benzyl or acyl. These compounds are pharmaceutically active and are especially useful in the treatment of disorders of the central nervous system. They are prepared by reacting an amine of formula R.sup.5 H with a triazolobenzodiazepine intermediate appropriately substituted at the 10-position or by ring-closing the appropriate anilinotriazole.
