Abstract

μέθοδος παρασκευής μιας ενώσεως του τύπου: [*] ένθα R1 και R2 επιλέγονται έκαστον από ομάδα αποτελουμένην από υδρογόνον και αλκύλιον R2 είναι κατώτερον αλκύλιον, και R4 και R5 επιλέγονται έκαστον από ομάδα αποτελουμένην από υδρογόνον και κατώτερον αλκανοϋλιον, του R5 όντος υδρογόνου οπόταν το R4 είναι υδρογόνον, ήτις περιλαμβάνει θέρμανσιν μιας κετόνης της δομής [*] εντός ενός ύδατικού αδρανούς διαλύτου άνω των 50ο Κ μετά μιας περισσείας ανθρακικού αμμωνίου και κυανιούχου καλίου, ανάκτησιν τουπροκύπτοντος προϊόντος τη συμπυκνώσει του μίγματος αντιδράσεως, θέσιν εις επαφήν του ειρημένου προϊόντος μετά μιας βάσεως προς σχηματισμόν του τριμεθοξυφαινυλοαμινοξέος, ανάκτησιν του εν λόγω αμινοξέος, υδρόλυσιν των ειρημένων μεθοξυλικών ομάδων τη προσθήκη του ειρημένου αμινοξέος εις πυκνόν υδροαλογονικόν οξύ και θέρμανσιν άνω των 135ο Κ, ανάκτησιν του τριϋδροξυφαινυλαμινοξέος, εστεροποίησιν, ειεπιθυμητόν, τη θερμάνσει του ειρημένου υδροξυφαινυλικού οξέος μετά μιας κατωτέρας αλκανόλης μιας καταλυτικής τουλάχιστον ποσότητος οξέος, και ακυλ επιθυμητόν, τη αντιδράσει του ειρημένου υδροξυφαινυλικού μεθ' ενός κατωτέρου αλκανοϊκού ανυδρίτου ή αλογονιδίου. Method of preparing a compound of the formula: [*] wherein R 1 and R 2 are selected each from a group consisting of hydrogen and alkyl R 2 is lower alkyl, and R 4 and R 5 are each selected from a group consisting of hydrogen and lower alkanoyl, [*] in an aqueous inert solvent above 50 ° C after an excess of ammonium carbonate and potassium cyanide, recovering the resulting product by concentrating the reaction mixture, contacting said product with a base to form trimethoxyxyphenylamino said addition of the amino acid to concentrated hydrohalic acid and heating above 135 ° C, recovery of the trihydroxyphenylamino acid, esterification of the desired, hydroxyphenyl with a lower alkanoic anhydride or halide.
