The present invention provides a novel nitrile compound useful as an intermediate for the production of, for example, N,N-substituted cyclic amine derivatives or phenylacetonitrile derivatives that are useful as a medicine. Specifically it provides a nitrile carboxylic acid compound, nitrile ester compound and nitrile alcohol compound. That is, it provides a nitrile compound represented by the following formula (I):
wherein R1 and R2 means substituents; m means 0 or an integer of from 1 to 6; n means 0 or an integer of from 1 to 5; and R3 means carboxyl group, a lower alkoxycarbonyl group or hydroxymethyl group.
本发明提供了一种新颖的腈化合物,可用作生产N,N-取代的环胺衍生物或苯乙腈衍生物的中间体,这些衍生物可用作药物。具体而言,它提供了一种腈羧酸化合物、腈酯化合物和腈醇化合物。也就是说,它提供了以下式(I)所表示的腈化合物:其中R1和R2表示取代基;m表示0或1至6的整数;n表示0或1至5的整数;R3表示羧基、较低的烷氧羰基或羟甲基基团。
