The biggest cause of ulcers in the stomach or duodenum is said to be excessive secretion of gastric acid, and a compound having an anticholinergic action as a so-called antiulcer agent for dealing with this, or a compound having an action of neutralizing gastric acid is used. Proposed. Moreover, it is known that the secretion of gastric acid is due to the stimulation of histamine H 2 receptor, and some of the substituted phenoxy derivatives, 2-guanidinothiazole derivatives, substituted furan derivatives, and substituted pyridyloxy derivatives have histamine H 2 receptor antagonism. It is also known to suppress the secretion of gastric acid (Japanese Patent Application Laid-Open No. 56-115750, Japanese Patent Publication No. 60-9750, Japanese Patent Application Laid-Open No. 54750).
