실험 절차

Intermediate 2.75 (120 mg, 0.33 mmol), (4-(4-(tert-butoxycarbonyl)piperazin-1-yl)phenyl)boronic acid (180 mg, 0.59 mmol), K3PO4 (240 mg, 1.1 mmol) and Bis[di-tert-butyl(4-dimethylaminophenyl)phosphine]dichloropalladium (II) (12 mg, 0.017 mmol) were taken up in 1,4-dioxane (5.3 mL) and water (0.53 mL). The stirred reaction mixture was heated to 100° C. for 2 h and was then cooled and partitioned between EtOAc, water and brine. The phases were separated and the aqueous phase was extracted with EtOAc. The combined organic phase was dried over Na2SO4, filtered, and concentrated. The crude residue was purified by silica gel chromatography (0-25% MeOH in DCM) to provide tert-butyl 4-(4-(1-cyclopropyl-7-((R)-1-((R)-5-oxopyrrolidin-3-yl)ethoxy)-1H-benzo[d]imidazol-5-yl)phenyl)piperazine-1-carboxylate. LCMS-ESI+ (m/z): [M+H]+ calcd for C31H40N5O4: 546.3; found: 546.1.
