反応手順
To a solution of N-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-2-(6-fluoro-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (60 mg, 0.083 mmol) in DMF (4 mL) was added 4-chlorobutan-2-one (11 mg, 0.1 mmol) followed by K2CO3 (34 mg, 0.25 mmol). The mixture was heated at 65° C. for 1.5 hours. After cooling to room temperature, the mixture was poured into water and filtered to give N-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-2-(6-fluoro-1-(3-oxobutyl)-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (40 mg, 61%). After drying, the crude was used into the next step without further purification. LCMS: (M+H)+=795.
