Versuchsvorschrift

To a stirred solution of t-butylnitrite (53.5 μL, 0.449 mmoles) in 1 ml sieve dried dimethylformamide at 50° C. under an atmosphere of nitrogen was added a solution of 4-amino-3,5-dibromobenzonitrile (50 mg, 0.179 mmoles) in 1 mL of DMF. The mixture was stirred at 50° C. for 0.5 hour and partitioned between diethyl ether, ice-water, and ammonium chloride. The organic phase was separated, washed with water and brine, dried over anhydrous sodium, filtered, and evaporated.
