Reaktionsschritte

5-Methyl-nicotinonitrile (2.08 g, 17.6 mmol) is heated at reflux in dry THF (20 mL) with MgMeBr (3 M solution in Et2O, 10 mL, 30 mmol) for 2 h. After cooling down, aq. Na2CO3 is added slowly to quench the reaction. Extractions with DCM affords the crude mixture which is purified by silica gel chromatography to yield 1-(5-methyl-pyridin-3-yl)-ethanone 18 (0.7 g, 30%). LC/MS (m/z) (M+1)+: 136.1.
