    • A process for producing an acridine carboxamide of formula (I) wherein each of R , R , R and R , which may be the same or different, is hydrogen or an organic substituent, x is an integer of 1 to 6 and Y is N(R)2 wherein R is C1-C6 alkyl, or a pharmaceutically acceptable salt thereof, which process comprises: (a) cyclising a compound of formula (II) wherein R , R , R and R are as defined above and R is C1-C6 alkyl, aryl or aryl-C1-C3 alkyl, by treatment with a Lewis acid in an organic solvent, to obtain a compound of formula (III) wherein R , R , R , R and R are as defined above; (b) treating either (i) the compound of formula (III) as defined above with a primary alkylamine of the formula (IV): NH2(CH2)xY, wherein x and Y are as defined above; or (ii) the carboxylic acid, obtainable by hydrolysing the compound of formula (III) as defined above under basic conditions, with a primary alkyl amine of formula the (IV) as defined above in the presence of a suitable coupling agent to obtain a compound of formula (I) as defined above; and (c) if desired, converting one compound of formula (I) into another compound of formula (I), and/or converting a compound of formula (I) into a pharmaceutically acceptable salt thereof. The aldehyde of formula (II) is obtained by oxidation of the corresponding alcohol, which in turn is produced by mild reduction of the corresponding carboxylic acid via an immidazolide intermediate.
    • 制备式(I)的吖啶甲酰胺的方法,其中R 1,R 2,R 5和R 6各自可以相同或不同,是氢或有机取代基, x是1至6的整数,Y是N(R)2,其中R是C 1 -C 6烷基或其药学上可接受的盐,该方法包括:(a)使式(II)的化合物环化,其中R 1 >,R 2,R 5和R 6如上所定义,R 3是C 1 -C 6烷基,芳基或芳基-C 1 -C 3烷基,通过在有机溶剂中用路易斯酸处理 ,得到其中R 1,R 2,R 3,R 5和R 6如上定义的式(III)化合物; (b)用式(IV)的伯烷基胺:NH 2(CH 2)x Y(其中x和Y如上定义)处理(i)如上定义的式(III)化合物; 或(ii)通过在碱性条件下水解上述式(III)化合物而得到的羧酸与式(IV)的伯烷基胺在合适的偶联剂存在下水解,得到 如上定义的式(I)化合物; 和(c)如果需要,将一种式(I)化合物转化为另一种式(I)化合物,和/或将式(I)化合物转化为其药学上可接受的盐。 通过氧化相应的醇获得式(II)的醛,其依次通过咪唑啉中间体温和还原相应的羧酸而产生。
