Versuchsvorschrift

Potassium carbonate (176 mg) in water (2 mL) was added to (S)-tert-butyl 4-(1-amino-1-oxo-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propan-2-ylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 16, step (i), 329 mg), 3-bromo-6-methyl-5H-pyrrolo[3,4-b]pyridin-7(6H)-one (Example 32, step (ii), 144 mg) and 1,1 bis(di-tert-butylphosphino)ferrocene palladium dichloride (50 mg) in degassed acetonitrile (12 mL) at 20° C. under nitrogen. The resulting solution was stirred at 80° C. for 90 min. The reaction mixture was cooled and filtered and the filtrate diluted with ethyl acetate, and washed with water. The aqueous was then extracted with dichloromethane and the combined organics dried over magnesium sulfate, filtered and evaporated to afford crude product. The crude product was purified by chromatography on silica eluting with methanol/ethyl:acetate (15:85 to 25:75). Pure fractions were evaporated to dryness to afford the sub-titled compound (278 mg).
