실험 절차

In a round-bottomed flask 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (120 mg, 0.27 mmol) was dissolved in DMF (1.2 ml). (S)-3,3-Dimethylbutan-2-amine (0.25 ml, 1.84 mmol) was added followed by HATU (114 mg, 0.30 mmol) and the yellow solution was stirred at room temperature overnight. Water was added and the resulting suspension was filtered. The filter cake was washed with water and petroleum ether then dried under high vacuum to afford 104 mg (73%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid ((S)-1,2,2-trimethyl-propyl)-amide as a light yellow powder.
