Compounds useful in the treatment of autoimmune disease are described by thefollowing general formula (I): n = 0-2 m = 0-2 m is not necessarily equal ton; where R1, R3 = NH2, F, Cl, C1-C4 alkoxy or phenoxy group, but R1 is notnecessarily equal to R3; and R2 = H, F, Cl, NH2, or NH- R- XH; where R = -(CH2)p - p = 2-4 = Formula (II), Formula (III) = Formula (IV) q = 0-3 X = CH2,NH, O, or S.
