반응 조건

반응 단계

12.23 g (149 mmol) of sodium acetate and then 7.66 ml (149 mmol) of bromine at 0° C. are added to 10 g (74.6 mmol) of a solution of 2-methoxy-nicotinonitrile in 29 ml of acetic acid. The reaction mixture is heated at 70° C. overnight. After returning to room temperature, the reaction medium is added to an ice bath and the precipitate obtained is filtered, rinsed with water and then dried at 50° C. to yield 11.6 g (73%) of 5-bromo-2-methoxy-nicotinonitrile in the form of a white solid.
