N-bromobutanimide → (2-Amino-5-bromopyridin-3-yl)(6-bromopyridin-2-yl)methanone

Participants

Reaction Steps

To a suspension of (2-aminopyridin-3-yl)(6-bromopyridin-2-yl)methanone (5.76 g, 20.7 mmol) in acetonitrile (120 ml) was added N-bromosuccinimide (4.05 g, 22.77 mmol). The resulting mixture was stirred at room temperature for 1 hour before mixture was concentrated in vacuo to approximately 20 ml. The solid was then collected by filtration and washed with minimal acetonitrile and dried to leave title compound as a brown solid (4.23 g, 57%). 1H NMR (DMSO-d6) 7.93-7.89 (4H, m), 8.03-7.99 (1H, m), 8.22 (1H, d), 8.36 (1H, d). ES+ 357.99.
