Versuchsvorschrift

2-Chloro-5-iodo-4-(tetrahydro-2H-pyran-4-yloxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (1 equiv), N-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinamide (1 equiv), 1′-bis(diphenyl-phosphino)-ferrocene]dichloropalladium(II) complex with dichloromethane (0.1 equiv), sodium carbonate (3 equiv) were suspended in a 3:1 mixture of 1,4-dioxane and water (0.09 M) were combined in a sealed reaction vessel. The resulting solution was flushed with nitrogen and stirred at 85° C. for 2 h. After cooling to room temperature the reaction mixture was loaded directly onto a silica-gel column and purified using flash chromatography (0-55% ethyl acetate in hexane). Fractions were combined, concentrated and the residue dried under high vacuum to give the title compound (61% yield) as a brown semi solid. MS (ESI) m/z 519.1 [M+1]+.
