실험 절차

To a solution of 2-phenoxy-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (0.10 g, 0.26 mmol), 4-dimethylaminopyridine (0.048 g, 0.39 mmol) and (3-dimethylamino-propyl)-ethyl-carbodiimide (0.075 g, 0.39 mmol) in CH2Cl2 (2 mL) was added (R)-2-amino-3-methyl-1-pyrrolidin-1-yl-butan-1-one (0.066 g, 0.39 mmol) in CH2Cl2 (0.5 mL). The reaction mixture was stirred at room temperature overnight, then quenched with water and extracted with ethyl acetate (3×). The organic layer was washed with water and saturated aqueous NaCl solution and dried over MgSO4, filtered and concentrated. The residue was purified by SiO2 column chromatography (0-100% EtOAc/hexanes) to afford 2-phenoxy-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [(R)-2-methyl-1-(pyrrolidine-1-carbonyl)-propyl]-amide as a yellow oil.
