Abstract

έθοδος παρασκευής ενώσεως αντιπροσωπευομένης υπό του τύπου (Ι) ενθα το Ζ αντιπροσωπεύει μέλος της ομάδος της αποτελουμένης από χλωρο,υδροξυ,και κυανο, το δε Χ αντιπροσωπεύει μέλος της ομάδος της αποτελουμένης από αμινο και κατώτερα αλκύλια, υπό τονόρο ότι οποτε το Ζ είναι υδροξυ το Χ είναι κατώτερον αλκύλιον, και η οποία περιλαμβάνει, συμπύκωνσιν μιάς 2-υδροξυ- ή 2-κυανο-υποκατεστημένης αιθυλοδραζίνης μετά 5-νιτρο-φουρφουράλης ή παραγώγου αυτής δυναμένου να υδρολυθή πρός τοιαύτην, κα ικαρβονυλίωσιν του εν λόγω προιόντος δι'ενός μέλους επιλεγμένου εκ της ομάδος της αποτελουμένης από ανυδρίτην κατωτέρου αλκανοικού οξέος και παράγοντας κυανιώσεως, επακολουθουμένην υπό του προαιρετικού ταδίου κατεργασίας τουδια υδροξυ υποατεστημένου προιόντος μετά θειονυλοχλωριδίου πρός σχηματισμόν του χλωρο υποκατεστημένου παραγώγου του ως άνω (χημικού) τύπου. process for the preparation of a compound represented by formula (I) wherein Z represents a member of the group consisting of chloro, hydroxy, and cyano, and X represents a member of the group consisting of amino and lower alkyls, provided that Z is hydroxy. X is lower alkyl, which comprises concentrating a 2-hydroxy- or 2-cyano-substituted ethyldrazine with 5-nitro-furfural or a derivative thereof which can be hydrolyzed therefrom by carbonation thereof for said from the group consisting of lower alkanic acid anhydride and cyanidizing agent, followed by the optional step of treating the hydroxy-substituted product with thionyl chloride to form the chloro-substituted derivative (its derivative).
