Procedure

A solution of (1H-benzo[d]imidazol-2-yl)(4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)methanone (0.350 g, 0.881 mmol) in DMF (5 mL) was treated with iodomethane (0.083 mL, 1.321 mmol). The mixture was stirred at RT and after 4 hours, it was diluted with water and extracted (2×) with DCM. The organic portions were combined 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, reduced and purified by column chromatography on silica gel using a gradient of 30 to 80% EtOAc in hexanes to afford (4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)(1-methyl-1H-benzo[d]imidazol-2-yl)methanone as white solid. MS (ESI, pos. ion) m/z: 411.9 (M+1). IC50 (uM) +++++.
