Abstract
Process for the production of benzothiazine derivatives of general formula I, ** (See formula) ** wherein R 1 signifies a hydrogen, chlorine or bromine atom or an alkoxy, alkylmercapto, alkylsulfonyl or alkylsulfinyl radical, each containing 1 to 4 carbon atoms inclusive, an aliphatic acyl radical containing from 2 to 4 carbon atoms inclusive , the trifluoromethyl radical or the cyano radical, and R2 means a hydrogen atom or an aliphatic acyl radical containing from 1 to 4 carbon atoms inclusive or the benzoyl radical, characterized in that a compound of general formula II is heated, ** (See formula) ** wherein R1 and R2 have the meanings indicated above, either in a suspension of carbonate or sodium or potassium bicarbonate in dimethyl formamide up to a temperature of 60-155º or with the addition of sodium or potassium hydroxide in acetone to boiling, obtaining a compound I, wherein R2 means a hydrogen atom, which compound I, when a compound I is required, wherein R2 means an aliphatic acyl radical containing from 1 to 4 carbon atoms inclusive or the benzoyl radical, acylates (Machine-translation by Google Translate, not legally binding)
