Procedure

To a stirred solution of 2-[(6S)-6-(3,5-difluorophenyl)-3,3-dimethyl-2-oxopiperidin-1-yl]-N-((2R)-2′-oxo-1′-{[2-(trimethylsilyl)ethoxy]methyl}-1,1′,2′,3-tetrahydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-5-yl]acetamide from Step A (47 mg, 0.07 mmol) in DMF (1 mL) at 0° C. was added NaH (11 mg of a 60% dispersion in oil, 0.28 mmol). After 15 min, iodomethane (30 mg, 0.21 mmol) was added and the mixture was allowed to warm to ambient temperature and was stirred for 1 h. The reaction mixture was quenched with H2O (5 mL) and the precipitate was isolated by filtration, washed with H2O, and dried in vacuo to provide the title compound. MS: m/z=675 (M+1).
