Reaction Steps

As shown in step 10-iii Scheme 10, 4-Chloro-2-(5,6-dimethoxypyridin-3-yl)-6-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-4-yl)-6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-one (Compound 82, 75 mg, 0.165 mmol and a degassed solution of 2M aqueous sodium carbonate (826 uL, 1.65 mmol] were suspended in 10 mL of toluene. The reaction mixture was purged with nitrogen for 5 minutes and tetrakistriphenylphosphine palladium(0) (38 mg, 0.033 mmol] was added, followed by the addition of 2 M triethylborate solution in THF (992 μL, 1.0 mmol). The reaction vessel was sealed and heated for 14 hours at 80° C. The reaction mixture was cooled and the volatiles removed under reduced pressure. The residue was dissolved in EtOAc/DCM 1:1 and filtered. The filtrate was concentrated under reduced pressure. The product was purified by preparative thin layer chromatography produced 2-(5,6-dimethoxypyridin-3-yl)-4-ethyl-6-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-4-yl)-6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-one (Compound 182, 1.1 mg): ESMS (M+1) 448.
