Abstract

"Process for the production of thieno-benzothiazine derivatives", of formula I, ** (See formula) ** in which: (a) R1 means a hydrogen, chlorine or bromine atom or an alkylmercapto radical containing from 1 to 4 carbon atoms inclusive, each of R2 and R3 signifying a hydrogen atom or the methyl radical, and each of R 4 and R 5 means an alkyl radical containing from 1 to 4 carbon atoms inclusive, or (b) R1, R2 and R3 have the meanings indicated above, and R4 and R5 together with the adjacent nitrogen atom form the piperidino radical, or (c) R1 has the meaning indicated above, R2 means a hydrogen atom, R4 means an alkyl radical containing from 1 to 4 carbon atoms inclusive, and R5 together with R3 means the trimethylene radical, characterized in that a compound of formula II is condensed in an inert solvent. ** (See formula) ** wherein R1 has the meaning indicated above, at a temperature between 75º C and the reflux temperature of the solvent used, with a compound of formula III, ** (See formula) ** wherein R2 to R5 have the meanings indicated above, and Hal means a chlorine, bromine or iodine atom, in the presence of an acid-binding agent.
