Procedure
A solution of 1.86 mL (21.00 mmol) of bromoacetylbromide in 10 mL of dichloromethane was added dropwise to a solution of 5.00 g (21.00 mmol) of 3-chloro-4-(2-diethylamino-ethoxy)-phenylamine. in 100 mL of dichloromethane at 0° C. and the mixture was stirred for 20 minutes at 0° C. The precipitate formed was filtered off, washed with dichloromethane and MTBE and dried i. vac. at 40° C.
