実験手順
A suspension of (1H-benzo[d]imidazol-2-yl)(4-(3-(tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)methanol (0.500 g, 1.245 mmol) in Chloroform (50 mL) and THF (50.0 mL) was treated with manganese dioxide (1.083 g, 12.45 mmol) at RT under nitrogen. The mixture was heated to 50° C. while stirring. After 40 mins, the reaction was filtered while warm through a small pad of celite. The filtrate was reduced and purified by column chromatography on silica gel using a gradient of 0 to 10% MeOH is DCM. The pure fractions were reduced and the residue was triturated in ethyl ether to give (1H-benzo[d]imidazol-2-yl)(4-(3-(tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)methanone as an off-white solid. MS (ESI, pos. ion) m/z: 399.9 (M+1). IC50 (uM) +++++.
