A series of novel 6-substituted imidazo[1,2-a]pyrazines were synthesized via palladium catalyzed amino- or alkoxycarbonylation as key step. The anti-secretory activity of these compounds has been assessed in a binding assay against H(+)/K(+)-ATPase from hog gastric mucosa. Some of the compounds proved to be potent inhibitors of the gastric acid pump.
