Versuchsvorschrift
A trifluoroacetic acid (3.0 mL) solution of the obtained tert-butyl 2-(2-hydroxy-5-(piperidin-1-yl)benzamido)-4-(2-methylphenyl)benzoate (0.063 g) was stirred at room temperature for 1 hour. The solvent was evaporated under reduced pressure, and water and ethanol were added thereto. After adjusting the pH to 5.5 with a saturated aqueous solution of sodium bicarbonate, the solid substance was collected by filtration to obtain 0.048 g of 2-(2-hydroxy-5-(piperidin-1-yl)benzamido)-4-(2-methylphenyl)benzoic acid as a yellow solid.
