YieldReaction ConditionsOperation in experiment
73% With 1,4-diaza-bicyclo[2.2.2]octane; In water; dimethyl sulfoxide; A mixture of <strong>[633328-95-7]5-bromo-2-chloro-4-methylpyrimidine</strong> (2.5 g, 12.08 mmol), sodium cyanide (600 mg, 12.24 mmol), and DABCO (500 mg, 4.46 mmol) in dimethyl sulfoxide (40 mL) and water (40 mL) was stirred overnight. The reaction mixture was diluted with H2O (100 mL) and extracted with ethyl acetate (80 mL×3). The ethyl acetate layers were combined, washed with brine (50 mL×2), dried over Na2SO4, filtered and concentrated. The residue was purified with silica-gel column chromatography (petroleum ether/ethyl acetate=10:1) to give 5-bromo-4-methyl-pyrimidine-2-carbonitrile (1.75 g, 73% yield) as a light yellow solid. LCMS (ESI) [M+H]+=199.9
67% With 1,4-diaza-bicyclo[2.2.2]octane; In water; dimethyl sulfoxide; at 20℃; for 12h; To a solution of sodium cyanide (6.18 g, 126.2 mmol) and DABCO (2.17 g, 19.41mmol) in DMSO:H20 (1:1, 200 mL) was added <strong>[633328-95-7]5-bromo-2-chloro-4-methylpyrimidine</strong>(20 g, 97.08 mmol in DMSO). The reaction mixture was stirred at room temperature for12 h, then diluted with water and extracted with ethyl acetate. The organic layer wasseparated and dried over sodium sulphate, then concentrated under reduced pressure. The residue was purified by silica gel column chromatography, using 20% ethyl acetate in hexanes as eluent, to afford the title compound (19 g, 67%) as a colourless oil. H (500 MHz, CDC13) 8.80 (s, 1H), 2.62-2.80 (m, 3H).
