Reaction Steps
The title compound is synthesized according to general procedure GP5 starting from 100 mg (0.28 mmol) 4-[2-Ethyl-3-(6-methylamino-pyridin-3-ylethynyl)-pyridin-4-yl]-2-fluoro-benzoic acid (A-46) using 55 μL (0.33 mmoL) N-ethyl piperazine, 101 mg (0.27 mmol) HATU and 50 μL DIPEA in 1.5 mL DMF. After completion of the reaction, the reaction mixture is filtered and the product is isolated from the obtained solution by RP-HPLC using a H2O/ACN-gradient. Yield: 82 mg (65%).
