Sodium Cyanide → 5-Bromopyrimidine-2-carbonitrile

関与物質

反応手順

Sodium cyanide (2.30 g, 46.6 mmol) was dissolved in dimethylformamide (60 ml) and treated with 5-bromo-2-chloropyrimidine (6.0 g, 31.1 mmol). The resulting mixture was stirred at room temperature for 18 hours, diluted with water and extracted with dichloromethane. The dichloromethane extracts were combined, washed with water, dried (magnesium sulphate), filtered and concentrated in vacuo. The crude product was purified by column chromatography eluting with a mixture of ethyl acetate:hexane (1:4) to afford the title compound (D38).
