合成路线1
该中间体在本合成路线中的序号：(III)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.
