Reaction Steps
A mixture of 4-aminobenzonitrile (220 mg; 1.89 mmol) and 6,8-dibromo-imidazo[1,2-a]pyrazine (500 mg; 1.81 mmol) is slurried in DMF (1 mL) and heated to 140° C. for 20 minutes. The reaction is allowed to cool, and when the bath reaches 75° C., ethyl acetate (40 mL) is added and the slurry is stirred to break up large solid lumps into fine powder. The powdered 4-(6-bromo-imidazo[1,2-a]pyrazin-8-ylamino)-benzonitrile is filtered, washed with diethyl ether (2×50 mL) and dried under vacuum to a fine orange/tan solid (600 mg).
