Abstract

ίς μέθοδος διά την κατασκευήν μιάς βενζιμιδεζόλης του τύπου (Ι) είς τον οποίον το R είναι μία πενταμελής ετεροσκαλική ρίζα περιέχουσα άζωτον και θείον, ή μέθοδος δε αύτη περιλαμβάνει την υποβολήν μιάς ενώσεως του γενικού τύπου (ΙΙ) είς αντίδρασιν με μίαν ένωσιν του συντακτικου τύπου (ΙΙΙ) είς τουςοποίους το NH2 είναι μία πενταμελής ετεροκυκλική ένωσις περιέχουσα άζωτον και θείον, το Β είναι μίαρίζα επιλεγομένη εκ της ομάδος ήτις αποτελειται εκ καρβοξυ ρίζηq, καρβο-αλκοζο-ρίζης, περβοζαμίδα-ρίζης, ακυλο-αλογονιδιου, και αλδευδο-ρίζης, και τοΧ επιλέγεται εκ της ομάδος ήτις αποτελείται έκ NH2, NO2, και NHR, ένθα το R' είναι εν κατώτερον αλκύλιον ή αλκενύλιον, και όταν το Β είναι μία αλδευδομάς, την οξείδωσιν του ενδιαμέσου προιόντος πρόςσχηματισμόν της βενζιμιδαζόλης, όταν δε το Y είναι μία νιτροομάς, την αναγωγήν του ενδιαμέσου προιόντος πρός σχηματισμόν της βενζιμιδεζόλης. A process for the manufacture of a benzimidezole of formula (I) in which R is a five-membered heteroscal radical containing nitrogen and sulfur, or a method comprising subjecting a compound of general formula (II) to reacting a compound of formula compound. (III) in which NH2 is a five-membered heterocyclic compound containing nitrogen and sulfur; and X is selected from the group as it consists of NH2, NO2, and NHR, wherein R 'is lower alkyl or alkenyl, and when B is an aldehyde, oxidation of the intermediate to form benzimidazole, and Y is nitro group, the reduction of the intermediate to form benzimidezole.
