Abstract

The present Invention includes synthetic steps and intermediates involved in the following reaction scheme a of converting compounds of Formula (II) to the diarylmethanes of Formula (I): ##STR1## wherein: Y is oxygen or sulfur; A, B, C, D, and E are carbon or 1, 2 or 3 of A, B, C, D, and E are independently nitrogen, and the others are carbon; and wherein R.sup.1 through R.sup.10 are selected independently from the group consisting of: hydrogen, hydroxy, alkyl, C.sub.3 -C.sub.8 cycloalkyl, C.sub.3 -C.sub.8 cycloalkyl alkyl, alkenyl, hydroxy alkyl, alkoxy alkyl, perhalo-alkyl, amino, nitro, nitrile, halo, carboxyl, sulfonyl, acyl, formyl, carbamoyl, trifluoromethyl, aminomethyl, azido, amido, hydrazino, aryl, aryloxy, heteroaryl, or aryl or heteroaryl, mono, di, or tri substituted with one or more hydrogen, hydroxy, alkyl, C.sub.3 -C.sub.8 cycloalkyl, C.sub.3 -C.sub.8 cycloalkyl alkyl, alkenyl, hydroxy alkyl, alkoxy alkyl, perhaloalkyl, amino, nitro, nitrile, halo, carboxyl, sulfonyl, acyl, formyl, carbamoyl, trifluoromethyl, aminomethyl, azido, amido, hydrazino, aryl, aryloxy, or heteroaryl groups and; the pharmaceutically acceptable salts and solvates thereof.
