0.29 mL (2.10 mmol) of triethylamine was added to a solution of 0.28 g (1.00 mmol) of 3-chloro-4-(2-diethylamino-ethoxy)-phenylamine-hydrochloride (intermediate product Z1b), 0.25 g (1.00 mmol) of (E)-3-(2-chloro-4-trifluoromethyl-phenyl)-acrylic acid (Z37b) and 0.34 g (1.05 mmol) of TBTU in 10 mL abs. THF and the mixture was stirred for 1 hour at RT. The reaction mixture was evaporated down i. vac. and the residue was combined with dichloromethane and water. The org. phase was separated off, washed with sat. aqueous sodium bicarbonate solution and water and evaporated down i. vac. The residue was purified by column chromatography (silica gel, gradient dichloromethane/10% conc. aqueous ammonia in MeOH 100:0→5:95).
