合成路线:By cyclocondensation of 2-aminobenzonitrile (I) with cyclohexanone (II) by means of ZnCl2 at high temperature.
合成路线:By nitration of acridine N-oxide (III) with H2SO4 - HNO3 to the corresponding 9-nitroacridine N-oxide (IV),followed by reduction with Fe - acetic acid.
合成路线:By cyclocondensation of isatine (V) with cyclohexanone (II) and aqueous concentrated NH3 at 150 C in a pressure vessel to acridine-9-carboxamide (VI),followed by a Hoffman degradation with Br2 and sodium methoxide in methanol
合成路线: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:This compound can be prepared by two different methods:1) By cyclocondensation of p-anisidine (I) with 2-oxocyclohexanecarboxylate (II) to 7-methoxy-1,2,3,4-tetrahydroacridone (III),which by treatment with refluxing POCl3 is converted to 9-chloro-7-methoxy-1,2,3,4-tetrahydroacridine (IV).This compound is converted to final product by treatment with NH3 in refluxing p-cresol.2) By cyclocondensation of 5-methoxyisatin (V) and cyclohexanone (VI) in concentrated aqueous ammonia at 150 C to 7-methoxy-1,2,3,4-tetrahydroacridine-9-carboxamide (VII),followed by a Hoffman degradation with potassium hypobromite.
