Procedure

To a solution of 5-[(6-chloropyridin-3-yl)methyl]-2-[(1S,2S)-2-hydroxycyclohexyl]-1,2-dihydro-3H-benzo[e]isoindol-3-one (0.040 g, 0.098 mmol) in 3 mL of tetrahydrofuran under an atmosphere of nitrogen was added dimethylzinc (1.2 M in tetrahydrofuran, 0.16 mL, 0.20 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloro-palladium(II), 1:1 complex with dichloromethane (7.2 mg, 0.0098 mmol). The mixture was heated at 50° C. for 3 hr and then cooled to ambient temperature. Additional dimethyl zinc (1.2 M in tetrahydrofuran, 0.16 mL, 0.20 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloro-palladium(II), 1:1 complex with dichloromethane (7.2 mg, 0.0098 mmol) were added and the mixture was heated at 50° C. for an additional 12 hr. The mixture was cooled to ambient temperature and concentrated in vacuo. The residue was purified via preparative reverse phase HPLC to provide the title compound that gave a proton NMR spectra consistent with theory and a mass ion (ES+) of 387.4 for [M+H]+: 1H NMR (400 MHz, CDCl3) δ 8.79 (s, 1H), 7.92-7.84 (m, 3H), 7.69 (s, 1H), 7.65-7.61 (m, 2H), 7.41 (d, J=8.1 Hz, 1H), 4.87-4.73 (m, 2H), 4.53 (s, 2H), 4.23-4.16 (m, 1H), 3.81-3.75 (m, 1H), 2.77 (s, 3H), 2.23-2.20 (m, 1H), 2.02-1.99 (m, 1H), 1.87-1.84 (m, 2H), 1.84-1.64 (m, 1H), 1.55-1.33 (m, 3H) ppm.
