Reaktionsschritte

Degassed a solution of (Z)-tert-butyl (tert-butoxycarbonylamino) ((1R,3S)-3-(2-chloro-5-fluoropyrimidin-4-ylamino)cyclohexylamino)methylenecarbamate, 70b, (0.200 g, 0.411 mmol), 5-fluoro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine, 44a, (0.205 g, 0.493 mmol) and Na2CO3 (0.616 mL of 2M solution, 1.232 mmol) in dimethoxyethane (15 mL) for 30 min. To the mixture was added palladium triphenylphosphane (0.023 g, 0.021 mmol) and the reaction mixture was heated in a pressure tube at 120° C. for 45 min. The reaction mixture was filtered through a pad of celite and the filtrate concentrated in vacuo. Attempted purification of the resulting residue by silica gel chromatography (10% MeOH/CH2Cl2) yielded a mixture containing mostly desired product that was used without further purification: LCMS RT=2.30 (M+H) 641.02.
