m-Chloro perbenzoic acid (6.2 g, 36.06 mmol) in CHCl3 (30 mL) was added drop wise to a solution of ethyl 2-(pyridin-3-yl)acetate (3.5 g, 21.21 mmol) in CHCl3 (30 mL) at room temperature under nitrogen atmosphere and the resulting reaction mass was stirred at room temperature for 5 hours. The reaction was monitored by TLC (10% methanol in chloroform). The reaction mass was basified using aqueous NaHCO3 solution to pH 7 and extracted using CHCl3. The organic layer was dried over sodium sulphate and concentrated under reduced pressure to afford 4.8 g of the crude product. LCMS: 60.09%, m/z=182.0 (M+1)
