A solution of (2R)-5-iodo-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (100.0 g, 276 mmol), sodium acetate (45.3 g, 552 mmol) and dichloro 1,1′-bis(diphenylphosphino)ferrocene palladium(II) dichloromethane adduct (11.3 g, 13.8 mmol) in a mixture of MeOH (1 L) and toluene (30 mL) was pressurized to 120 psi of CO at 23° C. and then heated at 80° C. for 12 h with stirring. The reaction mixture was diluted with water (1 L), and the precipitate collected by filtration, washed with water, and dried under nitrogen atmosphere to give the title compound, which was used without further purification. MS: m/z=295.3 (M+1).
