Procedure
5.0 mL of trifluoroacetic acid was added to the obtained tert-butyl 2-(benzamido)-4-(4-phenylpiperidin-1-yl)benzoate and stirred at room temperature for 3 hours, the solvent was evaporated under reduced pressure, ethyl acetate and water were added and pH was adjusted to pH 6.5 with a saturated sodium hydrogen carbonate aqueous solution. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with water and a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure. Diisopropyl ether was added to the obtained residue and a solid substance was separated by filtration to obtain 20 mg of 2-(benzamido)-4-(4-phenylpiperidin-1-yl)benzoic acid as white solid.
