tert-Butyl 5-(benzyloxy)-2-{(1-[4′-(hydroxymethyl)biphenyl-4-yl]piperidin-4-yl}methyl)-6-methylpyrimidine-4-carboxylate (0.81 g, 1.4 mmol) was dissolved in a mixed solvent of tetrahydrofuran (10 mL) and methanol (10 mL), and an aqueous sodium hydroxide solution (5 M, 10 mL, 50 mmol) was added, followed by stirring at 50° C. for 15 minutes. The reaction solution was cooled to room temperature, and hydrochloric acid (5 M, 10 mL, 50 mmol) was added, followed by extraction with ethyl acetate. The organic layer was concentrated under reduced pressure to afford 5-(benzyloxy)-2-{(1-[4′-(hydroxymethyl)biphenyl-4-yl]piperidin-4-yl}methyl)-6-methylpyrimidine-4-carboxylic acid as a yellow solid.
