Zusammenfassung:Novel pyrazolo[1,5-a]pyridine compounds are represented by the formula, [wherein R represents -OH, -OCH2-Ph (where Ph is a phenyl group), or -O-CH2-CH(OH)-CH2-NH-CH-(CH3)2; and R is H or, only when R is -OCH2-Ph, -COOH or -COOR (wherein R is a C1-C3 alkyl group)]. The compound of the above formula in which R is -O-CH2-CH(OH)-CH2-NH-CH-(CH3)2 has anti-serotonergic activity and can be synthesized, for example, by way of compounds of the above formula wherein R is OCH2Ph and R is COOR; R is -OH and R is H; and R is and R is H, in order. e
