Compounds of the formula (I): ##STR1## wherein R.sup.4 is hydrogen, D is oxygen or NR.sup.6, R.sup.1, R.sup.3, R.sup.6, R.sup.7 and R.sup.8 have defined values, and n is 1 or 2 are produced by internally cyclizing a compound of the formula (XV): ##STR2## wherein R.sup.19 is a value of R.sup.1 or hydrogen and, if R.sup.19 is hydrogen, reacting the cyclization product with R.sup.1 --Br and a weak base such as potassium carbonate.
Compounds of the formula (I): ##STR1## wherein R.sup.1, R.sup.3, R.sup.4, R.sup.7 and R.sup.8 are as described herein, D is oxygen or NR.sup.6, n is 1 or 2 and the physiologically acceptable salts thereof useful in reducing anxiety in an animal such as man. The compounds are potent anxiolytics having reduced side effects compared to known anxiolytics. Also pharmaceutical compositions, intermediates and methods of treatment and synthesis are described.
Compounds of the formula (I):
wherein D is oxygen or NR6, R1, R3, R4, R6, R7 and R8 have defined values, and n is 1 or 2, and pharmaceutically-acceptable acid-addition salts thereof, processes for their preparation, pharmaceutical compositions, and intermediates for preparing said compounds of the formula (I). The compounds of the formula (I) are central nervous system depressants, for example, anxiolytic agents.
