    • To provide a novel, industrially superior process for producing a 1,4-substituted cyclic amine compound which is useful as a pharmaceutical, and an intermediate for the process. That is, a process for producing an indole compound (I), which comprises reducing a 1,4-subsutituted 2-nitrophenyl compound (VII) to give a 1,4-substituted 2-aminophenyl compound (V); reacting the compound (V) with an N-substituted 4-piperidone compound (VI) to give a 1,4-substituted 2-piperidylaminophenyl compound (IV); cyclizing the compound (IV) to give a 2-oxoindoline compound (III); halogenating the compound (III) to give a 2-halogenated indole compound (II); reducing the compound (II); and if necessary subjecting the resulting compound to alcoholysis or aminolysis. wherein each of R1 and R2 represents a substituent; X represents a halogen atom; and n is a numerical subscript.
    • 提供一种工业上优异的制备用作药物的1,4-取代的环胺化合物的方法,以及该方法的中间体。 也就是说,制备吲哚化合物(I)的方法,其包括还原1,4-取代的2-硝基苯基化合物(VII)以得到1,4-取代的2-氨基苯基化合物(V); 使化合物(V)与N-取代的4-哌啶酮化合物(Ⅵ)反应,得到1,4-取代的2-哌啶基氨基苯基化合物(Ⅳ)。 使化合物(IV)环化,得到2-氧代二氢吲哚化合物(III); 卤化化合物(Ⅲ)得到2-卤代吲哚化合物(Ⅱ); 还原化合物(II); 并且如果需要,将所得化合物进行醇解或氨解。其中R 1和R 2各自表示取代基; X表示卤原子; n是数字下标。
