Abstract

"Process for the preparation of basically substituted thieno-benzothiapyran derivatives" of general formula I, ** (See formula) ** where R1 and R2 are hydrogen radicals or a methyl group and R3 and R4 each, an alkyl group having 1-4 carbon atoms or together by an alkylene chain, which may be interrupted, if appropriate, by a nitrogen atom substituted by a alkyl group with 1-4 carbon atoms, or for an oxygen atom or R4 is an alkyl group with 1-4 carbon atoms and R3 is linked with R1 by a di- or trimethylenic chain or R3 with R2 by a tri-chain - or tetramethylene and R5 is a halogen, an alkoxy- or alkyl-mercapto group with each time 1-4 carbon atoms, and their salts with organic or inorganic acids, characterized in that a compound of the general formula IV, ** (See formula) ** where R1 - R5 have the indicated meaning, it is subjected to a dissociation of water.
