Procedure
Under ice-cooling, trifluoroacetic acid (1.0 mL) was added to a methylene chloride (2.0 mL) solution of the obtained tert-butyl 2-(2-(methoxymethoxy)-5-((piperidin-1-yl)methyl)benzamido)-4-phenylbenzoate (0.080 g), followed by stirring at room temperature for 3 hours. The solvent was evaporated under reduced pressure, and ethyl acetate was added to the obtained residue. The solid substance was collected by filtration. Ethyl acetate (1.0 mL) and a 4.0 mol/L hydrogen chloride-dioxane solution (0.20 mL) were added to the obtained solid substance, followed by stirring at room temperature for 3 hours. The solid substance was collected from the reaction mixture by filtration to obtain 0.020 g of 2-(2-hydroxy-5-((piperidin-1-yl)methyl)benzamido)-4-phenylbenzoic acid hydrochloride as a white solid.
