Add triethylamine (40 mL, 287 mmol) and 20% palladium hydroxide on carbon (14 g) to a solution of 3-(6-chloro-5-fluoro-pyrimidin-4-yl)-2-[(1R)-1-(4-methoxyphenyl)ethyl]-3-methyl-6-(1-tetrahydropyran-2-ylpyrazol-4-yl)isoindolin-1-one (80 g, 142 mmol) in ethyl acetate (2.1 L) and hydrogenate with hydrogen gas (30 psi) at 20-25° C. for 16 hours. Repeat reaction conditions with 5 grams 3-(6-chloro-5-fluoro-pyrimidin-4-yl)-2-[(1R)-1-(4-methoxyphenyl)ethyl]-3-methyl-6-(1-tetrahydropyran-2-ylpyrazol-4-yl)isoindolin-1-one. Combine both reactions and filter through diatomaceous earth and evaporate to give the title compound as a yellow foam (77 g, 102%). ES/MS m/z: 528 (M+H).
