Reaktionsschritte

To a solution of methyl 3-(pyridin-2-yl)benzoate (300 mg, 1.40 mmol) in MeOH (3 mL) was added aqueous NaOH (1 mL, 0.4M). The mixture was stirred at room temperature for 3 h. The reaction solution was concentrated and the residue dissolved in water and adjust pH to 5-6 with 2N of HCl. The solution was extracted with EtOAc (3×20 mL) and the combined organic layers concentrated to give the desired crude product (450 mg, Yield 90%) which was used in the next step without further purification. LCMS (m/z): 200.1 (M+1).
