PROCESS FOR PREPARING NOVEL GUANIDINOTHIAZOLE COMPOUNDS Process for preparing novel guanidinothiazole compounds of the general formula: <IMG> wherein R represents a hydrogen atom or a lower alkyl group; R1 represents an amino group, a lower alkyl group, a halogeno lower alkyl group, a substituted- or unsubstituted-aryl group, a mono- or di-lower alkylamino group, an arylamino group or an aralkylamino group; R2 represents a hydrogen atom, a lower alkyl group, a lower alkenyl group or a lower alkynyl group; Y represents a sulfur atom or a methylene sroup; m and n, each represents an in-eger of 1 - 3; and the pharmacologically acceptable acid addition salts thereof. The guanidinothiazole compounds having gastric acid secretion inhibitors.
