PROCESS FOR PRODUCING 2-BRACKET-3-PHENYL-ISOXAZOL-5-YL-BRACKET CLOSED AENZOIC ACID DERIVATIVES AND SALTS AND HALOGENIDES FROM 3-COMMA ABOVE-PHENYL-SPIRO-SQUARE BRACKET-ISOBENZOFURANE-1-BRACKET-3H-BRACKET CLOSED,5-COMMA AAOVE-BRACKET-4-COMMA ABOVE-H-BRACKET CLOSED-ISOXAZOL-SQUARE BRACKET CLOSED-3-ONE DERIVATIVES

摘要

A process for preparing 2-(3-Aryl-5-isoxazolyl)-benzoic acid having the formula CHEM wherein X and Y are independently selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, halo-lower-alkyl, phenoxyphenyl and cyano, respectively its salts or halides, which comprises treating 3 min -(Aryl)spiro-[isobenzofuran-1(3H), 5 min (4 min H)-isoxazol]-3-one having the formula CHEM with respectively, heat, a strong base or a reactive halide and water.
