A solution of (4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)(1-methyl-1H-benzo[d]imidazol-2-yl)methanone (0.120 g, 0.292 mmol) in THF (10 mL) was evacuated and treated with Pd(OH)2 (20 mg) under nitrogen. The reaction was stirred under a hydrogen atmosphere with a balloon. After 24 hours, the reaction was filtered through a small plug of celite and the filtrate was treated with manganese dioxide (0.254 g, 2.92 mmol). The reaction was stirred at 50° C. for 1 hour and filtered through celite. The filtered was reduced under vacuum. The residue was taken up in DCM and washed (2×) with an aqueous saturated solution of sodium bicarbonate, then with water and then brine. The organic layer was then dried with sodium sulfate and purified by column chromatography on silica gel using a gradient of 30 to 80% EtOAc in hexanes to give (1-methyl-1H-benzo[d]imidazol-2-yl)(4-(3-(tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)methanone as a white solid. MS (ESI, pos. ion) m/z: 414.0. IC50 (uM) +++++.
