Reaction Conditions

Reaction Steps

0.25 mL of acetic acid and 4.1 μL of 2,5-dimethoxytetrahydrofuran were added sequentially to 10 mg of 2-(4-aminobenzamido)-4-phenoxybenzoic acid at room temperature and stirred at 90° C. for 5 minutes. After the reaction mixture was cooled so room temperature, ethyl acetate and a saturated sodium hydrogen carbonate aqueous solution were added. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium chloride aqueous solution, and the solvent was evaporated under reduced pressure. The obtained residue was purified wish silica gel column chromatography [PSQ100B (spherical) manufactured by Fuji Silysia Chemical Ltd., eluent; ethyl acetate] to obtain 3.8 mg of 4-phenoxy-2-(4-(1H-pyrrol-1-yl)benzamido)benzoic acid a brown solid.
