合成路线1

该中间体在本合成路线中的序号:(X)

The cyclocondensation of aniline (VII) with ethyl 2-oxocyclo-hexanecarboxylate (VIII) by means of HCl in refluxing benzene gives 9-acridone (IX), which by treatment with refluxing POCl3 is converted to 9-chloroacridine (X). Finally, this compound is treated with anhydrous NH3 in p-cresol), or with ethanolic ammonia with a Cu catalyst.
