Versuchsvorschrift

A round-bottomed flask was charged with 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 1-oxazol-2-yl-ethylamine dihydrochloride (crude from Step 3, 90 mg, 0.41 mmol). DMF (1.1 ml) was added followed by N,N-diisopropylethylamine (0.26 ml, 1.49 mmol) and HATU (95 mg, 0.25 mmol). The light yellow solution was stirred at room temperature for 48 h. Water was added and the resulting suspension was filtered. The solid was washed with water and petroleum ether then dried under high vacuum to afford 113 mg (93%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-oxazol-4-yl-ethyl)-amide as an off-white powder.
