合成路线1
该中间体在本合成路线中的序号：(XVIII)The reaction of (III) with (XI) by means of pyridine in THF gives 1,3-dioxo-2-isoindolineacetic acid [[N-(2-benzoyl-4-chlorophenyl)-1,3-dioxo-2-isoindolineacetamido]methylene]hydrazide (XVI), which by cyclization by means of trifluoroacetic acid in refluxing toluene yields 5-chloro-2-[3-(phtalimidomethyl)-4H-1,2,4-triazol-4-yl-benzophenone (XVII). The reaction of (XVII) with N,N,N',N'-tetramethyldiaminomethane (A) by means of acetyl chloride in DMF affords 5-chloro-2-[3-[(dimethylamino)methyl-5-(phthalimidomethyl)-4H-1,2,4-triazol-4-yl]benzophenone (XVIII), which is finally cyclized by means of hydrazine in hot ethanol.
