실험 절차

1-(4-((1-(tert-Butoxycarbonyl)piperidin-3-yl)methylamino)-6-(5-cyanopyrazin-2-ylamino)pyridin-3-yl)-1H-pyrrole-3-carboxylic acid (80 mg, 0.154 mmol) was dissolved in DMF (1.5 mL). 2-(tert-Butyldimethylsilyloxy)ethanamine (41 mg, 0.230 mmol), N-ethyldiisopropylamine (30 mg, 0.230 mmol), 1-hydroxy benzotriazole hydrate (31 mg, 0.230 mmol) and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide (44 mg, 0.23 mmol) were added to the solution and the reaction mixture was stirred for 14 h at room temperature. The solution was partitioned between dichloromethane and water. The two phases were separated and the aqueous phase was extracted with dichloromethane. The combined organic phases were dried (Na2SO4) and evaporated to give tert-butyl 3-((5-(3-(2-(tert-butyldimethylsilyloxy)ethylcarbamoyl)-1H-pyrrol-1-yl)-2-(5-cyanopyrazin-2-ylamino)pyridin-4-ylamino)methyl)piperidine-1-carboxylate (80 mg, 78%) which was used in the next step without purification.
