실험 절차

To a solution of N-tert-butyl-2-(6-fluoro-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (80 mg, 0.135 mmol) in DMF (5 mL) was added 2-(2,2-dimethyl-1,3-dioxolan-4-yl)ethyl methanesulfonate (36 mg, 0.162 mmol) followed by K2CO3 (56 mg, 0.405 mmol). The mixture was heated at 65° C. for 4 hours. After cooling to room temperature, the mixture was poured into water, filtered and dried to give N-tert-butyl-2-(1-(2-(2,2-dimethyl-1,3-dioxolan-4-yl)ethyl)-6-fluoro-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (90 mg, 92%) The crude was used to the next step without purification. LCMS: (M+H)+=723.
