And the patent contained the following:
The invention relates to preparation of benzenesulfonamides of formula I, as stereoisomers, enantiomers, tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates or prodrugs thereof, for the treatment of diseases or conditions associated with voltage-gated sodium channels, such as epilepsy. Compounds I wherein A is a direct bond, R1 is (un)substituted cycloalkyl, aryl, monocyclic heteroaryl, etc.; R2 is (un)substituted 5-membered or 6-membered heteroaryl; R3 is O, S(O)t, etc.; R6 is H, halo, haloalkyl; R7 is alkyl, alkenyl, halo, etc.; q is 1,2 or 3; t is 0, 1 or 2, are claimed. Compounds I were evaluated for their biol. activity in bioassays (data given). Compounds I can be used in the treatment of voltage-gated sodium channel-mediated diseases. The experimental process involved the reaction of 2-(Bromomethyl)-6-fluorobenzonitrile(cas: 1261686-95-6).Quality Control of 2-(Bromomethyl)-6-fluorobenzonitrile
