Sodium hydride → HCID 57975861, compound

Participants

Reaction Steps

Dimethylacetamide (10 ml) was added slowly to a mixture of 2-chloropyrimidine (1 g, 8.7 mmol), sodium hydride (0.8 g, 34.9 mmol), and 4-bromo-2-fluoro-aniline (1.6 g, 8.7 mmol) and the resulting mixture was stirred overnight at room temperature. Water was added slowly and the resulting mixture extracted three times with ethyl acetate. The organic phase bas washed with brine, dried over sodium sulfate and concentrated to dryness. Flash chromatography on silica gel chromatography using a gradient of ethyl acetate and hexane afforded (4-bromo-2-fluoro-phenyl)-pyrimidin-2-yl-amine (1.3 g, 56% yield). 1H NMR (500 MHz, DMSO-d6) δ 6.85 (m, 1H), 7.37 (d, 1H), 7.55 (d, 1H), 7.74 (m, 1H), 8.44 (s, 2H), 9.21 (s, 1H). MS: m/z 269.0 (M+H+).
