Abstract

Process for the production of thieno-benzothiapyran derivatives of formula I ** (See formula) ** wherein R 1 signifies an alkylsulfonyl radical containing from 1 to 4 carbon atoms inclusive or the trifluoromethyl radical, and R 2 signifies an alkyl radical containing from 1 to 4 carbon atoms inclusive, and its acid addition salts, characterized by than a thieno-benzothiapyran derivative of formula III, ** (See formula) ** wherein R1 and R2 have the meanings indicated above, treated with a water dissociating agent or subjected to dry heating to dissociate the water elements and, when an acid addition salt is required, the compound is reacted resulting from formula I with an organic or inorganic acid.
