Process for the preparation of benzothiazepinone derivatives

Benzothiazepinone derivatives can be prepared by alkaline hydrolysis of benzothiazoles to give o-amino-thiophenols, isolation thereof by acidification and further reaction with acrylic acids. In this connection, the acidification is carried out using a mineral acid, after which the o-amino-thiophenol is extracted using a water-insoluble solvent and is reacted in this extract with an acrylic acid.
