Abstract
Provided are cycloheptenopyridine derivatives represented by the general formula ##STR1## [wherein R represents a hydrogen atom or lower alkyl group; R.sup.1 represents a hydrogen atom, halogen atom, lower cycloalkoxy group, amido group, substituted phenoxy group, substituted benzyloxy group, lower alkoxy group optionally containing halogen atoms(s), nitro group, hydroxyl group, lower alkenyloxy group, lower alkylthio group, or a group--NR.sup.4 R.sup.5 (wherein R.sup.4 and R.sup.5 may be the same or different and each represent a hydrogen atom or lower alkyl group, or R.sup.4 and R.sup.5 mutually combine together with the nitrogen atom adjacent thereto to form a 5- or 6-membered heterocyclic group); R.sup.2 represents a hydrogen atom, halogen atom, lower alkyl group optionally containing a halogen atom, lower alkoxy group optionally containing a halogen atom, hydroxyl group, acyl group, lower alkoxycarbonyl group, nitro group or amino group; R.sup.3 represents a hydrogen atom, a lower alkyl group, lower alkoxymethyl group, lower alkylcarbonyl group, lower alkoxycarbonyl group, carbamoyl group, lower alkylcarbamoyl group, lower alkylcarbonylmethyl group, lower alkoxycarbonyl group,…
