Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 85 words
A compound of formula I ##STR14## wherein R 1 and R 2 independently are hydrogen, halogen of atomic number from 9 to 35, alkoxy (C 1-4 ) or alkyl (C 1-4 ), R 3 and R 4 either are independently hydrogen or alkyl (C 1-6 ), or together with the nitrogen atom to which they are bound form a pyrrolidino, piperidino, perhydrazepino, morpholino or 4-alkyl(C 1-4 )piperazinyl radical, and R 5 is hydrogen or alkyl(C 1-4 ), or a pharmaceutically acceptable acid addition salt thereof.
Claim 2
Dependent Claim 85 words
