실험 절차

To a solution of N-((4-chloro-2,6-dimethoxypyrimidin-5-yl)methyl)-3-cyclopropyl-1-ethyl-1H-pyrazol-5-amine (2.42 g, 7.16 mmol) in DME (50 mL) and water (15 mL) was added 4,4,5,5-tetramethyl-2-vinyl-1,3,2-dioxaborolane (2.5 mL, 14.3 mmol), Pd(Ph3P)4 (0.828 g, 0.716 mmol) and sodium carbonate (2.47 g, 23.3 mmol). The mixture was sparged with argon for 15 min and then heated at reflux for 18 h. The mixture was then absorbed onto silica gel and dried under reduced pressure. After dry loading, the product was purified by FCC (10-75% EtOAc/heptane) to give 3-cyclopropyl-N-((2,4-dimethoxy-6-vinylpyrimidin-5-yl)methyl)-1-ethyl-1H-pyrazol-5-amine. MS (ESI+) m/z 330.1 (M+H)+.
