89% With lithium hexamethyldisilazane; In tetrahydrofuran; diethyl ether; at 0 - 20℃; for 16h;Inert atmosphere; The solution of <strong>[57381-44-9]5-bromo-2-chlorobenzonitrile</strong> (10 g, 46 mmol) in diethyl ether (100 ml_) was dropwise added to LiHMDS (1 M in tetrahydrofuran, 92 ml_) with stirring under nitrogen atmosphere at 0 C. The resulting solution was stirred at 0 C ~ room temperature for 16 h. The resulting solution was quenched with 3N hydrochloric acid (100 ml_) at 0 C. The water phase was collected, the pH of the water phase was adjusted to 14 with NaOH aqueous, extracted with ethyl acetate (100 ml_x3). The combined organic phases were washed with brine (100 ml_), dried over anhydrous Na2S04 and evaporated in vacuo. This resulted in 5-bromo-2-chlorobenzimidamide (13 g, 89 % yield) as a brown solid.
