摘要

IMIDAZO ¢4,5-b! PYRIDINE COMPOUNDS AND PROCESS FOR PREPARING SAME Imidazo¢4,5-b!pyridine compounds of the general formula ¢I! are provided: <IMG> ¢I! where R1 is straight-chain or branched C1-8 alkoxy which may be substituted with cycloalkyl, or C2-4 fluoroalkyloxy, R2 is H, methyl or methoxy, and R3 and R4 are each H or methyl and may be the same or different. All these compounds have good activity of inhibiting potassium ion-dependent adenosine triphosphatase and excellent storage stability, so that they are usable for the treatment of gastric and/or duodenal ulcers.
