Abstract:
1. A compound of the formula II in which q is 1–5, R 1 is halogen; lower alkyl; hydroxyl; lower alkanoyloxy; lower alkoxy which is unsubstituted or substituted by hydroxyl, lower alkoxy or carboxyl; a radical of the formula —O(—CH 2 —CH 2 —O) t —R 6 , in which t is 2–5 and R 6 is hydrogen or lower alkyl; carboxyl; lower alkoxycarbonyl; piperazin-1-yl-carbonyl; carbamoyl; N-lower alkyl-carbamoyl which is unsubstituted in the lower alkyl moiety or substituted by hydroxyl or amino; N,N-di-lower alkyl-carbamoyl; cyano; nitro; amino; lower alkanoylamino; lower alkylamino; N,N-di-lower alkylamino; aminosulfonyl or trifluoromethyl, where, if more than one radical R 1 is present in the molecule, these can be identical or different from one another, R 2 is hydrogen, carbamoyl or N-lower alkyl-carbamoyl, m and n are each 0 or 1, where m is 0 if n is 1 and m is 1 if n is 0, dashed lines represent a single bond which is located between N-7 and C-8 if m is 0 and located between C-8 and N-9 if m is 1, R 3 is lower alkyl or phenyl which are unsubstituted or in each case substituted by hydroxyl, lower alkoxy, amino, lower alkylamino or N,N-di-lower alkylamino and Y is a suitable leaving group, it being possible for free functional groups present therein to be protected by easily detachable protective groups, or a salt thereof.
