ABSTRACT:
There is presented compounds of the formula ##STR1## wherein A is selected from the group consisting of ##STR2## R.sub.1 is selected from the group consisting of hydrogen, chlorine, bromine, lower alkyl, the group NR.sub.4 R.sub.5, the group --CH.sub.2 --CO--R.sub.7, the group--NH(CH.sub.2).sub.m NR.sub.8 R.sub.9, hydroxy, lower alkoxy, mercapto and lower alkyl mercapto; R.sub.2 is selected from the group consisting of hydrogen, amino and dilower alkyl amino; R.sub.3 is selected from the group consisting of hydrogen, lower acyloxy and hydroxy; X is selected from the group consisting of hydrogen, halogen, trifluoromethyl, ethyl, .alpha.-hydroxy ethyl and acetyl; Y is hydrogen or halogen; R.sub.4 and R.sub.5 are hydrogen or lower alkyl or together with their co-bonded nitrogen atom form a five to seven membered heterocyclic group; R.sub.7 is selected from the group consisting of hydroxy lower alkoxy and NR.sub.8 R.sub.9 ; R.sub.8 and R.sub.9 are hydrogen or lower alkyl; n is 0 or 1 and m is 1 to 7 with the limitations that (1) at least one of R.sub.1 and R.sub.2 are hydrogen, (2) when R.sub.3 is lower acyloxy or hydroxy, A is the group (a), X is hydrogen, halogen, trifluoromethyl, ethyl or acetyl and R.sub.1 is the group --NH(CH.sub.2).sub.m NR.sub.8 R.sub.9, then R.sub.8 and R.sub.9 are lower alkyl, (3) when A is group (d) and R.sub.1 is the group --NH(CH.sub.2).sub.m NR.sub.8 R.sub.9 then R.sub.8 and R.sub.9 are lower alkyl and (4) when n is 1, R.sub.1 is hydrogen, lower alkyl, lower alkoxy, chlorine, bromine or the group --CH.sub.2 --CO-- R.sub.7 with R.sub.7 as above then A is the group (a) or (b) and the pharmaceutically acceptable salts thereof.
The compounds exhibit pharmacological activity as anxiolytics and sedatives.
Also presented Are various novel intermediates and processes to produce the above end products.
