Claim 1

A compound having the formula ##STR818## wherein R 1 is the same or different and is selected from the group consisting of alkyl of one through three carbons, inclusive, alkoxy of one through three carbons, inclusive, trihaloalkyl of one or two carbons, hydroxy, halo, trihaloalkoxy of one or two carbons and o-methylenedioxy with the proviso that at least one R 1 is hydroxy, alkoxy or o-methylenedioxy; a is one through three; R 2 through R 7 are the same or different and are selected from the group consisting of hydrogen, alkyl of one through three carbons, inclusive, hydroxy, alkoxy of one through three carbons; phenyl; halo; cycloalkyl of three through six carbons when R 2 and R 3 , R 4 and R 5 , or R 6 and R 7 are taken together with the carbon to which they are attached; cycloalkyl of four through seven carbons when R 2 and R 4 or R 4 and R 6 are taken together with the carbons to which they are attached; and cycloalkyl of five or six carbons, with the overall provisos that no more than one ring may be attached to any one carbon and that at least two of R 2 through R 7 are hydrogen; R 8 is alkyl of one through three carbons, hydrogen, or phenyl unsubstituted or substituted with a maximum of three substituents selected from the group consisting of alkyl of one through three carbons, halo, alkoxy of one through three carbons, and trihaloalkyl of one to two carbons; and A' is selected from the group consisting of --(CH 2 ) m OCH 2 CH 2 B and --(CH 2 ) m --(OCH 2 CH 2 ) q B', wherein B is selected from the group consisting of halo, and ##STR819## wherein R' is selected from the group consisting of alkyl of from one to three carbon atoms, nitro, halo and trifluoromethyl; B' is selected from the group consisting of halo, hydroxy and ##STR820## wherein R' is the same as above, and m is one to three and q is two to three.
