The residue was diluted with saturated NaHCO3 aqueous solution and extracted with CHCl3. The organic layer was dried over Na2SO4 and concentrated in vacuo. The residue was purified by column chromatography on silica gel (CHCl3/MeOH) to afford methyl 4'-(morpholin-4-yl)biphenyl-3-carboxylate (531 mg, 77%). To a solution of methyl 4'-(morpholin-4-yl)biphenyl-3-carboxylate (531 mg, 1.79 mmol) in EtOH (10 mL) was added 1M NaOH aqueous solution (5.00 mL, 5.00 mmol). The mixture was stirred at 60 C for 3 h. After being cooled to room temperature, the mixture was neutralized with 1M HCl aqueous solution. The resulting precipitate was filtered to give the product (470 mg, 93%) as a solid.
