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.

合成路线2
该中间体在本合成路线中的序号:(IV)Anthranitic acid (I) is reacted with cyclohexanone (II) to give 5-hydroxy-1,2,3,4-tetrahydroacridine (III). The hydroxy compound (III) is then reacted with phosphorous oxychloride to give 5-chloro-1,2,3,4-tetrahydroacridine (IV). Aminolysis of (IV) with n-butylamine affords centbucridine.
