Reaction Steps

To a solution of 3,5-dichloro-4-((1-cyclohexyl-2-oxopyrrolidin-3-yl)methyl)phenyl trifluoromethanesulfonate (Example 240) (1.34 g, 2.83 mmol) in THF (30 mL) in a round bottom flask was added 3-cyano-4-fluorophenylboronic acid (560 mg, 3.39 mmol), sodium carbonate (900 mg, 8.48 mmol) and water (10 mL). The mixture was stirred at 60° C. for 5 minutes, palladium tetrakis (163 mg, 0.14 mmol) was added. Reaction mixture was brought to 80° C. and stirred for 3 hours. Cooled and partitioned between ethyl acetate and HCL(1 N). Organic was separated, wash with water, brine; dry over sodium sulfate, filter, and concentrate. Purify by silica gel (25-50% ethyl acetate in hexane) to afford 1.10 g (88%) of the title compound: Mass spectrum (LCMS) m/z=445.0 (M+H).
