Versuchsvorschrift

A solution of tert-butyl (1S,2R)-2-(4-chloro-2-(2,4-dimethoxybenzyl)-7-fluoro-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)cyclohexylcarbamate (35 mg, 0.064 mmol), 1-(difluoromethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (18.67 mg, 0.076 mmol) and bis(triphenylphosphine)palladium chloride (44.7 mg, 0.064 mmol) in dioxane (500 μL) and saturated aq Na2CO3 (500 μL) was heated at 85° C. for 2 h. After filtering out the solids, the solvent was removed and the residue was dissolved in MeOH and DCM and purified by preparative HPLC. The fractions were collected and ACN was removed via rotary evaporation. The resulting aq solution was neutralized with saturated aq NaHCO3, washed with EtOAc (2×200 mL), dried over Na2SO4, and filtered. The organic phase was stripped to dryness via rotary evaporation to yield the title compound (36 mg, 90%). [M+H] calc'd for C31H37F3N6O5, 631. found, 631.
