Versuchsvorschrift

To a stirred solution of methyl-2-(chloromethyl)nicotinate (20 g, 108 mmol) in DCM (300 mL) was added m-CPBA (20.5 g, 119 mmol) at 0° C. After it was stirred at room temperature for 16 hours, the reaction mixture was washed with a mixture of satd. aq. Na2SO3 and NaHCO3 solution. The organic layer was dried over anhy. Na2SO4, filtered, and concentrated in vacuo to give the crude title product (20 g, yield 92%), which was used in the next step reaction without further purification.
