To a solution of NaH (330 mg, 13.7 mmol) in DMF (10 mL) was added pyridin-3-ylmethanol (500 mg, 4.6 mmol) and the solution was stirred at 27° C. for 20 minutes. Ethyl 2-bromoacetate (921.8 mg, 5.52 mmol) was then added and the reaction mixture stirred at 27° C. for further 16 h. Once the reaction was complete by TLC analysis, the mixture was quenched by addition of water (50 mL) and extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine (30 mL), dried over Na2SO4 and concentrated to give the Ethyl 2-(pyridin-3-ylmethoxy)acetate (600 mg, 66.8%) as colorless oil which was used in next step without further purification. LCMS: 196.1 [M+H]+.
