Komponenten

Versuchsvorschrift

Sodium hydride (55% in mineral oil, 0.13 g) was added to a solution of 3-(5-bromo-pyridin-2-yl)-1-methyl-pyrrolidin-2-one (0.69 g) in N,N-dimethylformamide (10 mL) at room temperature. The resulting mixture was stirred in the presence of air for 1.5 h and then diluted with ethyl acetate. The precipitate formed thereafter was separated by filtration, washed with ether, and dried. The title compound was obtained as a colorless solid. Yield: 0.71 g (93% of theory); LC (method 1): tR=1.38 min; Mass spectrum (ESI+): m/z=271/273 (Br) [M+H]+.
