Imidazopyridine derivatives (I) are new. Imidazopyridine derivatives of formula (I), their enantiomers, diastereoisomers, and their salts with acids and bases are new. R1 = H, halogen, alkyl, polyhaloalkyl, CN, NO2, hydroxycarbonyl, alkoxycarbonyl, aminocarbonyl, or dialkylaminocarbonyl; R2 = H, alkyl, aryl (optionally substituted), heteroaryl (optionally substituted) or a group of formula R20-C(X)-; R20 = alkyl, alkoxy, amino, alkylamino, dialkylamino, aryl (optionally substituted), or heteroaryl (optionally substituted); X = O, S, or NR21; R21, R3 = H or alkyl; n = 1-6; and N = pyrido ring with the N atom in the 1, 2, 3, or 4 positions. Alkyl and alkoxy groups have 1-6 C atoms, aryl is phenyl or naphthyl, polyhaloalkyl groups having 1-3 C atoms and 1-7 halogen atoms, heteroaryl groups may be mono or bicyclic of 5 - 11 ring atoms, at least one ring being aromatic, and having 2 or 3 heteroatoms (O, N, S) and may be substituted by 1-3 alkyl groups. Optional substituents on aryl groups may be 1 or 2 substituents selected from halogens, alkyl, alkoxy, polyhaloalkyl, hydroxy, CN, NO2, amino, alkylamino, dialkylamino, carboxyl, amido, and -COO-alkyl groups, and heteroaryl groups having a non-aromatic ring may be further substituted on this non-aromatic ring by oxo. |
