Disclosed are compounds of the formula:
or the pharmaceutically acceptable acid addition salts thereof wherein:
R1 and R2 are the same or different and represent hydrogen, C1-C6 alkyl, halogen, hydroxy, amino, cyano, nitro, trifluoromethyl, trifluoromethoxy, C1-C6 alkoxy, —O2CR′, —NHCOR′, —COR′, —SOmR′, where R′ is C1-C6 alkyl and wherein m is 0, 1 or 2; or
R1 and R2 independently represent —CONR′R″, or —NR′R″ where R′ and R″ independently represent hydrogen or C1-C6 alkyl;
R3 is hydrogen, C1-C6 alkyl, or —COR′″ where R′″ is C1-C6 alkyl;
