Reaction Steps

Sodium hydride (55% in mineral oil, 0.17 g) was added to a solution of 3-(5-bromo-pyridin-2-yl)-1-methyl-pyrrolidin-2-one (0.77 g) and methyl iodide (0.44 mL) in N,N-dimethylformamide (15 mL) in argon atmosphere at room temperature. The resulting mixture was stirred at room temperature overnight. Water and ethyl acetate were then added and the organic phase of the resulting mixture was separated. The organic phase was washed with brine, dried (MgSO4), and concentrated. The residue was chromatographed on silica gel (dichloro-methane/ethyl acetate 1:1) to give the title compound as a colorless oil. Yield: 0.50 g (61% of theory); LC (method 1): tR=1.60 min; Mass spectrum (ESI+): m/z=269/271 (Br) [M+H]+.
