Reaction Steps

A toluene solution (5 mL) containing the intermediate from Step A (441 mg, 2.4 mmol), 4-(trifluoromethoxy)phenyl boronic acid (746 mg, 3.62 mmol), K3PO4 (865 mg, 4.08 mmol), 2-(dicyclohexylphosphino)biphenyl (68 mg, 0.19 mmol) and Pd(OAc)2 (22 mg, 0.098 mmol) was heated at 100° C. under an argon atmosphere. After 1 hour the solution was partitioned between water and ethyl acetate. The organic phase washed with 1N NaOH, brine, dried over MgSO4 and concentrated. The residue was purified by silica gel chromatography using a hexanes/ethyl acetate gradient to give the title compound. LCMS1 3.71 min. (M+H)=309.
