2-Chloro-4-trifluoromethylaniline → N-[3-chloro-4-(2-diethylamino-ethoxy)-phenyl]-2-(2-chloro-4-trifluoromethyl-phenylamino)-acetamide

Participants

Reaction Steps

A solution of 0.228 g (0.511 mmol) of 2-bromo-N-[3-chloro-4-(2-diethylamino-ethoxy)-phenyl]-acetamide-hydrobromide (intermediate product Z1c) and 0.200 g (1.023 mmol) of 2-chloro-4-trifluoromethyl-phenylamine in 5 mL DMF was stirred for 16 hours at 90° C. and then for 24 hours at 120° C. The reaction mixture was cooled to RT, diluted with water and exhaustively extracted with EtOAc. The combined org. extracts were dried over magnesium sulphate and evaporated down i. vac. The residue was dissolved in DMF and purified by HPLC-MS (Stable Bond C18; 3.5 μm; water:acetonitrile:formic acid 9:1:0.01→1:9:0.01 over 9 min).
