A novel anti-serotonergic compound and the synthetic intermediates thereof are provided. The compound and intermediates are pyrazolo[1,5-a]pyridine compounds represented by the formula, ##STR1## wherein R.sup.1 represents --OH, --OCH.sub.2 -Ph (where Ph is a phenyl group), ##STR2## or --O--CH.sub.2 --CH(OH)--CH.sub.2 --NH--CH(CH.sub.3).sub.2 ; and R.sup.2 is H or --COOR (wherein R is a C.sub.1 -C.sub.3 alkyl group). Among the compounds of the above formula, a compound wherein R.sup.1 is --O--CH.sub.2 --CH(OH)--CH.sub.2 --NH--CH(CH.sub.3).sub.2 has anti-serotonergic activity and can be synthesized, for example, by way of compounds wherein R.sup.1 is OCH.sub.2 Ph and R.sup.2 is COOR, R.sup.1 is --OH and R.sup.2 is H, and R.sup.1 is ##STR3## and R.sup.2 is H, in order.
提供了一种新型的抗血清素化合物及其合成中间体。该化合物和中间体是由以下式表示的吡唑并[1,5-a]吡啶化合物,其中R.sup.1代表--OH,--OCH.sub.2 -Ph(其中Ph是苯基),或--O--CH.sub.2 --CH(OH)--CH.sub.2 --NH--CH(CH.sub.3).sub.2;而R.sup.2为H或--COOR(其中R是C.sub.1-C.sub.3烷基)。在上述式的化合物中,当R.sup.1为--O--CH.sub.2 --CH(OH)--CH.sub.2 --NH--CH(CH.sub.3).sub.2时具有抗血清素活性,例如,可以通过其中R.sup.1为OCH.sub.2 Ph和R.sup.2为COOR的化合物,R.sup.1为--OH和R.sup.2为H的化合物,以及R.sup.1为##STR3##和R.sup.2为H的化合物,依次合成。
