Reaction Steps

A mixture of (1H-benzo[d]imidazol-2-yl)(4-(3-chloropyrazin-2-yloxy)phenyl)methanone (300 mg, 0.855 mmol), potassium phosphate (545 mg, 2.57 mmol), 2-(trifluoromethyl)pyridin-4-ylboronic acid (490 mg, 2.57 mmol), and Bis-[4-(di-tert-butylphosphino)-N,N-dimethylbenzenamine]palladium dichloride (121 mg, 0.171 mmol) in dimethoxyethane was heated to 80° C. Following complete reaction, the mixture was cooled to room temperature which caused a solid to precipitate which was collected by filtration and dried to give (1H-benzo[d]imidazol-2-yl)(4-(3-(2-(trifluoromethyl)pyridin-4-yl)pyrazin-2-yloxy)phenyl)methanone. MS (ESI, pos. ion) m/z: 461.0 (M+1). IC50 (uM) +++++.
