Versuchsvorschrift

To a solution of (R)-1-(4-trifluoromethyl-pyridin-2-yl)-ethylamine dihydrochloride (89 mg, 0.34 mmol) in DMF (2 mL) was added N,N-diisopropylethylamine (0.20 mL, 1.13 mmol), 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (100 mg, 0.23 mmol), and HATU (95 mg, 0.25 mmol). The yellow reaction mixture was stirred at room temperature overnight then quenched with water and extracted with EtOAc (3×). The combined organics were washed with water (3×) and brine then dried over MgSO4 and concentrated. The residue was purified by silica gel chromatography with 50% to 100% EtOAc/hexanes to give 122 mg (88%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [(R)-1-(4-trifluoromethyl-pyridin-2-yl)-ethyl]-amide as a white solid.
