65 mg (0.47 mmol) of potassium carbonate was added to a solution of 70 mg (0.159 mmol) of 2-bromo-N-[3-chloro-4-(2-diethylamino-ethoxy)-phenyl]-acetamide-hydrobromide (intermediate product Z1c) and 64 mg (0.314 mmol) of 3-chloro-biphenyl-4-ol in 1 mL of abs. DMF and the mixture was stirred for 1 hour at 40° C. and for 15 hours at RT. The reaction mixture was diluted with dichloromethane, the org. phase was washed with sat. aqueous sodium bicarbonate solution and water and dried over magnesium sulphate. Column chromatography (silica gel, dichloromethane/MeOH 9:1) yielded the product.
