反应详情

To a solution of methyl 3-(pyridin-4-yl)benzoate (450 mg, 2.1 mmol) in MeOH (5 mL) was added an aqueous solution of NaOH (1.5 mL, 0.4M). The mixture was stirred at room temperature for 2 h. The reaction solution was then concentrated, the residue was next dissolved in water and adjusted pH to 5-6 with the 2N HCl. After extraction with EtOAc, the organic layers were dried and concentrated to give the product desired (600 mg, Yield 90%). LCMS (m/z): 200.1 (M+1).
