On January 25, 1990, Yoshikawa, Yoshinari; Ochi, Yutaka; Sekiuchi, Kazuto; Saito, Hideji; Hatayama, Katsuo published a patent.HPLC of Formula: 34662-29-8 The title of the patent was Preparation of sulfonanilide derivatives as antiinflammatory agents. And the patent contained the following:
Sulfonanilides [I; R1 = C1-4 alkyl; R2 = C1-4 alkyl, Ph, AR4 wherein R4 = Ph, halo-substituted Ph or cycloalkyl, A = O, S; R3 = halo, haloalkyl, Ph, CHO, alkoxycarbonyl, etc.] are prepared Reduction of 5.0 g nitro compound II (R = NO2) in EtOH over 5% Pd-C gave 4.4 g amine II (R = NH2), which (3.3 g) was diazotized and the diazonium salt treated with KCN to give 1.2 g cyano compound II (R = cyano) (III). III at 50 mg/kg p.o. showed 48.9% inhibition of carrageenan-induced edema in rats, vs. 41.6% inhibition with ibuprofen. Also prepared were 35 addnl. I. The experimental process involved the reaction of 3-Chloro-4-nitrobenzonitrile(cas: 34662-29-8).HPLC of Formula: 34662-29-8
