Abstract

A procedure for the preparation of thienothiazine derivatives of the general formula **(See formula)** in which A together with the two carbon atoms to which it is attached forms the group **(See formula)** and the dashed line represents the double bond present in group (a); R1 represents a lower alkyl group; R2 represents the radical of an aromatic heterocyclic ring containing from 1 to 4 heteroatoms, which may be substituted by one or two lower alkyl groups, or a phenyl group which may be substituted by halogen, hydroxyl, lower alkyl, trifluoromethyl or alkoxy. lower and R3 and R4 each represent a hydrogen atom or a lower alkyl group, the process of which comprises hydrolyze an enamine of the general formula **(See formula)** in which A, R1 and R2 have the meaning indicated above and R5 and R6 each represent lower alkyl or form, together with the nitrogen atom to which they are attached, an anillompyrrolinic, pyrrolidinic, piperidinic, morpholinic or N- (lower alkyl) -piperazinic.
