are directed to substituents on the benzene ring and to R and R substituents on atom1 2
number 3 of the indane structure. Three alternatives are included in the claimed subject
matter. If the substituents on the benzene ring are both NO then R and R on the indane2, 1 2
structure are unsubstituted. If one substituent on the benzene ring is NO and the other is
2
hydrogen, then both R and R substituents on atom number 3 of the indane structure must1 2
be other than hydrogen. If the substituents on the benzene ring are selected from the group
of hydrogen, alkyl, -CF , -NH , sulfamino, and mono and dialkyl amino, then R and R on the3 2 1 2
indane structure contains two constituents individually selected from the group consisting of
hydrogen, alkyl of 1 to 5 carbon atoms or together with the carbon atom to which they are
attached form cycloalkyl of 3 to 6 carbon atoms.
THE CLAIMS
Claim 33 is illustrative of appellants’ invention and is reproduced in the attached
appendix.
