Abstract
έθοδος πρός παρασκευήν 1-φαινυλο-3-μεθοξυ-5-σουλφανιλαμιδο-πυραζόλης-1,2, χαρακτηριζομένη κατά τούτο, ότι σουλφονυλ-αλογονίδια του τύπου (Ι) ένθα το W σημαίνει αμινομάδα ή έν πρός αμινομάδα δυνάμενοννα μεταταπή υπόλοιπον, συμπυκνούμεν μετά 5-αμινο-πυραζολών του τύπου (ΙΙ) ένθα το Χ σημαίνει μεθοξυομάδα ή παριστά μίαν υδροξυλομάδα ή έν πρός ΟΗ-ομάδα δυνάμενον να μετατραπή υπόλοιπον, οπότε το Χ ενδεχομένως μεταγενεστέρως μετατρέπεται, κατά γνωστόν καθ'εαυτόν τρόπον, είς την μεθοξυομάδα, ή συμπυκνούμεν σουλφοναμίδια του τύπου (ΙΙΙ), ένθα το W έχει την ανωτέρω δοθείσαν σημασίαν, ή τα αλκαλικά αυτών άλατα μετά 5-αλογονο-πυραζολών του τύπου (ΙV) ένθα το Χ έχει την ανωτέρω δοθείσαν σημασίαν οπότετο Χ ενδεχομένως μεταγενεστέρως μετατρέπεται, κατά γνωστόν καθ'εαυτόν τρόπον, είς την εθοξυομάδα, μετα ταύτα δε μετατρέπομεν ενδεχομένως το W είς τηναμινομάδα. Process for the preparation of 1-phenyl-3-methoxy-5-sulfanylamido-pyrazole-1,2, characterized in that the sulfonyl halides of formula (I) in W mean an amino group or to an amino group having a residual transition moiety, concentrated after -amino-pyrazoles of formula (II) wherein X means a methoxy group or represents a hydroxyl group or an OH group which can be converted to a residue, wherein X may subsequently be converted, as is known therein, to the methoxy group, or to the methoxy group. of formula (III), wherein W has the above meaning, or their alkali salts after 5-halo-pyrazoles of formula (IV) wherein X has the above meaning, wherein X may be subsequently converted, as is known per se Thus, in the ethoxy group, after that we do not possibly convert W to the amino group.
