実験手順
To a solution of racemic methyl-3-[(2-chloro-5-fluoro-pyrimidin-4-yl)amino]-2-hydroxy-1-methyl-cyclohexanecarboxylate, 66e, (0.65 g, 2.05 mmol) and 5-chloro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine (1.32 g, 3.05 mmol) in THF (20 mL) was added aqueous Na2CO3 (3.52 mL of 2 M solution, 7.04 mmol). The solution was degassed with N2 for 20 minutes. Tetrakis triphenylphosphane palladium (O) (0.14 g, 0.12 mmol) was added and the mixture was refluxed overnight. LCMS showed good conversion, but some starting materials remained. More degassed 2 N Na2CO3 was added followed by another portion of Tetrakis triphenylphosphane palladium (0.14 g, 0.12 mmol). The reaction was refluxed for another 4 hours. The mixture was cooled to room temperature, extracted with EtOAc. The organic phase was washed by brine and dried over Na2SO4. After evaporation of solvent the crude mixture was purified by silica gel chromatography (Hexanes/EtOAc 100/0 to 0/100) to provide 1.0 g of racemic methyl-3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]-2-hydroxy-1-methyl-cyclohexanecarboxylate, 66f. LCMS: 588.26 (M+1).
