Abstract
There are prepared 7-azabenzimidazoles of the formula ##STR1## where R.sub.1 and R.sub.2 are the same or different and are hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.6 -alkanol or --NR.sub.1 R.sub.2 is a 5 to 7 membered saturated heterocyclic ring having either one nitrogen atom, one nitrogen atom and one oxygen atom or two nitrogen atoms, R.sub.3 is hydroxy, an amino group, a mono C.sub.1 -C.sub.6 -Alkylamino group, a di-C.sub.1 -C.sub.6 -alkylamino group, or a C.sub.2 -C.sub.6 -alkylamino, di-C.sub.1 -C.sub.6 -alkylamino, mercapto, C.sub.1 -C.sub.6 -alkylmercapto, hydroxy or C.sub.1 -C.sub.6 -alkoxy, R.sub.5 is hydrogen or halogen and A is a C.sub.2 -C.sub.6 -alkylene group or a salt of such compound. Preferably R.sub.1 and R.sub.2 are two equal C.sub.1 -C.sub.6 -alkyl groups or --NR.sub.1 R.sub.2 is piperidino, pyrrolidino, morpholino, homopiperidino, piperazino or homopiperazino, R.sub.3 is hydroxy, mercapto, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylmercapto or C.sub.1 -C.sub.6 -alkylmino, mercapto, C.sub.1 -C.sub.6 -alkylmercapto, hydroxy or C.sub.1 -C.sub.6 -alkoxy and R.sub.5 is hydrogen and salts thereof. The compounds are useful in treating ulcers and gastritis.
