Versuchsvorschrift

Tetrakis triphenylphosphine (62 mg, 0.05 mmol) was added to a dioxane (5 ml)-water (1 ml) suspension of 2-chloro-6-[(3S)-3-methylmorpholin-4-yl]-9-(2,2,2-trifluoroethyl)-9H-purine (361 mg, 1.08 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (261 mg, 1.18 mmol), and sodium carbonate (342 mg, 3.23 mmol). The reaction mixture was heated to reflux for 2.5 hours and returned to room temperature. Water was added to the reaction mixture and the resulting mixture was extracted with 10% methanol-chloroform. The organic layer was dried over anhydrous magnesium sulfate and, after filtration, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform to chloroform:methanol=15:1) to give a solid. The resulting solid was washed with 50% ethyl acetate-hexane and dried to give the title compound (423 mg) as a powder.
