실험 절차

1,4-Dioxane (40 ml), water (20 ml), and sodium carbonate (2 g, 19 mmol) were added to N-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (1.45 g, 6.18 mmol) and 2-chloro-6-morpholin-4-yl-9-(tetrahydrofuran-3-ylmethyl)-9H-purine (2.0 g, 6.18 mmol) and the atmosphere in the reaction vessel was substituted with nitrogen. Tetrakis triphenylphosphine palladium (0.36 g, 0.31 mmol) was added, then the atmosphere in the reaction vessel was substituted with nitrogen again, and the resulting mixture was heated to reflux for 3 hours. The reaction mixture was partitioned with ethyl acetate and water, the organic layer was dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. Methylene chloride-ether was added to the residue and the insoluble matter was collected by filtration and dried to give the title compound (1.0 g, 41%) as a white solid.
