実験手順

In a 25 ml round-bottomed flask, 2-(5-difluoromethoxy-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid tert-butylamide (120 mg, 0.23 mmol) was dissolved in DMF (1.7 ml). The light yellow solution was cooled to 0° C. and sodium hydride (60% in mineral oil, 37 mg, 0.93 mmol) was added. The reaction was stirred at 0° C. for 15 min then 3-(bromomethyl)pyridine hydrobromide (91 mg, 0.36 mmol) was added. The reaction mixture was stirred at 0° C. for 1 h then quenched with water and diluted with petroleum ether. The suspension was filtered, washed with water and petroleum ether and the product collected was dried under high vacuum to afford 126 mg (90%) of 2-(5-difluoromethoxy-1-pyridin-3-ylmethyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid tert-butylamide as a yellow powder.
