Методика

In one embodiment, the compounds can be prepared as shown in Scheme II. A dihydroxy benzoic acid methyl ester is reacted with benzyl chloride, to produce a Bis-benzyloxy benzoic acid methyl ester (1). The Bis-benzyloxy benzoic acid methyl ester can then be heated with LiOH to give a Bis-benzyloxy benzoic acid (2). The Bis-benzyloxy benzoic acid (2) is then reacted with an aminophenyl to produce a phenyl-benzamide (3). The phenyl-benzamide (3) is then reacted with hydrazine to give a triazol (4). The hydroxy groups can then be unprotecxted in the presence of palladium on charcoal to give the final product.
