Patent ID: 6881733

Claim:
The compounds of Formula I: where: R is hydrogen, halo, trifluoromethyl or C 1 -C 6 alkyl; R 1 is hydrogen, halo, trifluoromethyl, phenyl, or C 1 -C 6 alkyl; R 2 , R 3 , and R 4 are independently hydrogen, halo, trifluoromethyl, cyano, C 1 -C 4 alkoxy, C 1 -C 4 alkoxycarbonyl, C 1 -C 6 alkyl, C 1 -C 6 alkyl substituted with a substituent selected from the group consisting of C 1 -C 4 alkoxy and hydroxy, or —C(O)NHR 9 ; R 9 is C 1 -C 8 alkyl where the alkyl chain is optionally substituted with a substituent selected from the group consisting of phenyl and pyridyl; A is attached at either the 4- or 7-position of the benzofuran nucleus and is an amine of formula: n is 0, 1, or 2; R 5 , R 6 , and R 7 are independently hydrogen or C 1 -C 4 alkyl; Q is hydrogen; R 5′ is hydrogen or methyl, provided that R 5′ may be methyl only when R 5 is other than hydrogen, or R 5′ and Q taken together with the carbon atoms to which they are attached form a double bond; R 6′ is hydrogen or methyl, provided that R 6′ may be methyl only when R 6 is other than hydrogen, or R 6′ and Q taken together with the carbon atoms to which they are attached form a double bond; R 7′ is hydrogen or methyl, provided that R 7′ may be methyl only when R 7 is other than hydrogen; or pharmaceutically acceptable acid addition salts thereof subject to the following provisos: a) when n is 1 or 2, at least one of R 5 , R 6 , and R 7 , must be other than hydrogen; and b) no more than two of R 5 , R 5′ , R 6 , R 6′ , R 7 , and R 7′ may be other than hydrogen.
