To a solution of N-tert-butyl-2-(5-(difluoromethoxy)-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (100 mg, 0.156 mmol) in DMF (4 mL) was added 4-chlorobutan-2-one (20 mg, 0.187 mmol) followed by K2CO3 (65 mg, 0.468 mmol). The mixture was heated at 65° C. for 1.5 hours. After cooling to room temperature, the mixture was poured into water, filtered and dried to give N-tert-butyl-2-(5-(difluoromethoxy)-1-(3-oxobutyl)-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide. The crude product was used in the next step without purification. MS: (M+H)+=713.
