実験手順

Intermediate 2.64 (24 mg, 0.073 mmol), 4-morpholinophenylboronic acid (33 mg, 0.16 mmol), Bis[di-tert-butyl(4-dimethylaminophenyl)phosphine]dichloropalladium(II) (1.7 mg, 0.0024 mmol) and K3PO4 (52 mg, 0.25 mmol) were taken up in 1,4-dioxane (0.9 mL) under Ar. Water (0.1 mL) was added and the resulting stirred mixture was heated to 100° C. After 1.75 h, the reaction mixture was cooled to r.t. and was diluted with EtOAc (2 mL), water (1 mL), and brine (1 mL). The phases were separated, and the aqueous phase was extracted with EtOAc (4×1.5 mL). The combined organic phase was dried over Na2SO4, filtered, and concentrated. The resulting crude residue was purified by silica gel chromatography (0% to 15% MeOH in DCM) to afford (R)-4-((R)-1-(3-(difluoromethyl)-6-(4-morpholinophenyl)-3H-imidazo[4,5-c]pyridin-4-yloxy)ethyl)pyrrolidin-2-one 3.24.
