Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
125 words
A method for ganglionic blocking which comprises administering an effective amount of a compound of the formula ##STR4## and the pharmaceutically acceptable salts thereof, wherein X 1 and X 2 each represent a member selected from the group consisting of hydrogen, halo, trifluoromethyl, acyl, alkyl, hydroxy, alkoxy and amino, R 1 , R 2 , and R 3 each represent a member selected from the group consisting of hydrogen, lower alkyl and lower alkenyl and R represents a member selected from the group consisting of cycloalkyl, cycloalkenyl and aryl, also, R 3 and either R 1 or R 2 can constitute a methylene bridge, --(CH 2 ) 2 -- or --(CH 2 ) 3 --, resulting in the formation of a five- or six-membered ring.
Claim 2
Independent Claim
125 words
A method for ganglionic blocking which comprises administering an effective amount of a compound of the formula ##STR4## and the pharmaceutically acceptable salts thereof, wherein X 1 and X 2 each represent a member selected from the group consisting of hydrogen, halo, trifluoromethyl, acyl, alkyl, hydroxy, alkoxy and amino, R 1 , R 2 , and R 3 each represent a member selected from the group consisting of hydrogen, lower alkyl and lower alkenyl and R represents a member selected from the group consisting of cycloalkyl, cycloalkenyl and aryl, also, R 3 and either R 1 or R 2 can constitute a methylene bridge, --(CH 2 ) 2 -- or --(CH 2 ) 3 --, resulting in the formation of a five- or six-membered ring.
Claim 3
Dependent Claim
12 words
