To a solution of methyl 4-{8-[(4-methyl-5-trifluoromethyl-2-bromophenyl)methyl]-2-oxo-1-oxa-3,8-diazaspiro[4.5]dec-3-yl}benzoate (30 mg, 0.055 mmol) in dioxane (1.5 mL) and water (0.5 mL) in a 5 mL microwave reaction vial were added 2,3,4-trifluorophenylboronic acid (20 mg, 0.111 mmol), 1,1′-bis(diphenylphosphino)ferrocene palladium (II) dichloride dichloromethane complex (9 mg, 0.011 mmol) and lithium hydroxide mono-hydrate (5 mg, 0.111 mmol). The reaction was heated in a microwave at 120° C. for 15-30 minutes. The crude reaction was diluted with acetonitrile and water, filtered and purified by reverse phase chromatography using a gradient of acetonitrile and water with 0.1% ammonium hydroxide. Lypholization of the desired fractions afforded the title compound (13.4 mg) as a white solid.
