Abstract

ία μέθοδος δια την παρασκευήν μιας ενώσεως 1,1-διοξειδίου της βενζοθειαζίνης, εχούσης ένα εκ των γενικών ταυτομερών συντακτικών τύπων: [*] εις τους οποίους το R1 επιλέγεται εκ της ομάδος ήτις αποτελείται εξ υδρογόνου, και μιας κατωτέρας αλκυλικήςρίζης, ήτις περιλαμβάνει την υπαγωγήν ενός δισουλφονυλοχλωριδίου της νιτροανιλίνης, έχοντος τον γενικόνσυντακτικόν τύπον: [*] εις τον οποίον το R1 έχει την ανωτέρω δοθείσαν σημασίαν, εις αντίδρασιν μετ'αμμωνίας εις μίαν ποσότητα μεγαλυτέραν της απαιτουμένης προς σχηματισμόν του αντιστοίχου δισουλφοναμιδίου της νιτροακιλίνης, το οποιον ακολούθως φέρεται εις αντίδρασιν με μίαν ένωσιν επιλεογμένην εκ της ομάδος ήτις αποτελείται εκ μυρμηκικού οξέος και των παραγώγων τούτου και μιγμάτων των ενώσεων τούτων, εις μίαν ποσότητα μεγαλυτέραν ενός γραμμομοριακού ισοδυνάμου. A process for the preparation of a benzothiazine 1,1-dioxide compound having one of the general tautomeric structural formulas: [*] wherein R1 is selected from the group consisting of hydrogen and a lower alkyl radical, comprising the addition of a nitroaniline disulfonyl chloride having the general structural formula: [*] wherein R1 has the above significance, in reaction with ammonia in an amount greater than that required to form the corresponding nitroacillin disulfonamide, which is then reacted with a murine derivatives thereof and mixtures of these compounds, in an amount greater than one molar equivalent.
