Procedure
Ethyl acetate and water were added to 2-(4-fluoroanilino)-4-(2-methoxypyridin-5-yl)benzoic acid trifluoroacetate, and it was adjusted to pH6.0 with saturated sodium hydrogen carbonate aqueous solution. The organic layer was separated and collected,dried over anhydrous magnesium sulfate after sequential washing with water and saturated sodium chloride aqueous solution, and the solvent was removed under reduced pressure. Hexane was added to the obtained residue, and solid matter was filtrated to give 2-(4-fluoroanilino)-4-(2-methoxypyridin-5-yl)benzoic acid 15 mg of pale yellow solid.
