The present invention provides substituted pyrazolo[1,5-a]pyridine derivatives expressed by a compound of the general formula (I), ##STR1## (wherein: X is hydrogen atom or methyl group; R is hydrogen atom, straight or branched lower alkyl group, lower alkoxy group, lower alkylthio group, dialkylamino group, alkyleneimino group, and morpholino group; R.sub.1 is different from R and is hydrogen atom, straight or branched lower alkyl group, lower alkoxy alkyl group, and dialkylamino group). The compound of the present invention can be prepared by reacting a compound of the general formula (II), ##STR2## in which X and R are as shown hereinbefore, with a compound of the general formula (III), in which R.sub.1 is as shown hereinbefore, R.sub.1 COOH (III) or with a functional derivative of the compound of the general formula (III).
本发明提供了一种由通式(I)化合物表达的取代的吡唑并[1,5-a]吡啶衍生物,其中:X是氢原子或甲基基团;R是氢原子、直链或支链低级烷基基团、低级烷氧基基团、低级烷基硫基基团、二烷基氨基基团、烷基亚氨基基团和吗啉基团;R1与R不同,是氢原子、直链或支链低级烷基基团、低级烷氧基烷基基团和二烷基氨基基团。本发明的化合物可以通过将通式(II)化合物(其中X和R如上所述)与通式(III)化合物反应而制备得到,其中R1如上所述,R1 COOH(III)或通式(III)化合物的功能衍生物。
