Versuchsvorschrift

In a round-bottomed flask, (cis-3-amino-cyclopentyl)-acetonitrile trifluoroacetate (crude from Step 6) was dissolved in DMF (1.3 ml) and N,N-diisopropylethylamine (0.65 ml, 3.72 mmol) was added. Then, 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (110 mg, 0.25 mmol) and HATU (104 mg, 0.27 mmol) were added. The yellow solution was stirred at room temperature for 48 h. Water and petroleum ether were added and the resulting suspension was filtered. The filter cake was washed with water and petroleum ether then dried under high vacuum to afford 128 mg (94%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (cis-3-cyanomethyl-cyclopentyl)-amide as an off-white powder.
