(I; R1 = H, acyl, PhCO, R2CO2R3; Y = H, alkali metal ion; R2 = alkylidene; R3 = H, alkyl, alkali metal ion), were prepd. There are some commonly used reagents like 720-94-5 in this article. Thus, 2-aminooxypropionic acid hydrochloride and NaOAc in dioxane/H2O were treated dropwise with 4-(5-p-methylphenyl-3-trifluoromethylpyrazol-1-yl)benzenesulfonyl chloride (prepn. given) in dioxane to give 96% 2-[4-(5-p-methylphenyl-3-trifluoromethylpyrazol-1-yl)benzenesulfonylami noxy]propionic acid. The latter at 3 mg/kg orally in rats gave 21% inhibition of carrageenan induced edema after 4 h, vs. 16% for Celecoxib. .
