YieldReaction ConditionsOperation in experiment
70% With potassium hexamethylsilazane; In tetrahydrofuran; at -78 - 20℃; for 4h; Potassium bis(trimethylsilyl)amide (25 mL, 12.5 mmol, 0.5M in toluene) was added to a solution of <strong>[709652-82-4]2-amino-5-bromo-nicotinonitrile</strong> (496 mg, 2.5 mmol) in THF (10 mL) at -78 0C which was followed by a dropwise addition of acetyl chloride (533 muL, 7.5 mmol). The reaction was stirred at ambient temperature for 4 h then quenched with ammonium chloride (10 mL, sat). The resulting mixture was extracted with methylene chloride; the organic layer was washed with water and dried over MgSO_j. The volatiles were removed under vacuum to give the title compound (420 mg, 70%). 1H NMR (300 MHz, DMSO-4 delta): 10.92 (s, IH), 8.82 (d, J = 2.3Hz, IH), 8.66 (d, J= 2.3Hz, IH), 2.12 (s, 3H). MS (ESI) m/e: 240 and 242 (M+H)+.
