Add sodium bis(trimethylsilyl)amide (210 mL, 210 mmol, 1 M THF) drop wise over 60 minutes to an ice cold suspension of 2-[(1R)-1-(4-methoxyphenyl)ethyl]-3-methyl-6-(1-tetrahydropyran-2-ylpyrazol-4-yl)isoindolin-1-one (62 g, 144 mmol) and 4,6-dichloro-5-fluoropyrimidine (31 g, 186 mmol) in tetrahydrofuran (620 mL). Stir the solution 60 minutes at 0° C. and then dilute the mixture with ethyl acetate (1 L) and water (1 L). Wash the organic phase with saturated aqueous sodium chloride and evaporate under reduced pressure. Dissolve the residue in 1:1 petroleum ether/ethyl acetate, filter through a pad of silica gel, and evaporate to give the title compound as a yellow foam (83 g, 103%). ES/MS m/z: 562 (M+H).
