合成路线图解说明:

The reaction of 2-(benzyloxy)aniline (I) with acetic anhydride and pyridine gives the acetanilide (II), which is treated with P2S5 in hot toluene to yield the thioacetamide (III). The reaction of (III) with methyl iodide and K2CO3 in hot acetonitrile affords the methylated thioimidate (IV), which is cyclized with biphenyl-4-carbohydrazide (V) in hot DMF to provide 4-(2-benzyloxyphenyl)-3-(4-biphenylyl)-5-methyl-4H-1,2,4-triazole (VI). The hydrogenation of (VI) with H2 over Pd/C in methanol gives the corresponding phenol (VII), which is finally alkylated by means of 4-(2-chloroethyl)morpholine (VIII) and NaH in hot DMF to yield the target triazole.
