Reaction Steps

To a mixture of cesium carbonate (0.223 g, 0.684 mmol) and 2-(1-(3-chloropyrazin-2-yl)azetidin-3-yl)-5-methyl-1H-benzo[d]imidazole (0.103 g, 0.344 mmol) was added NMP (1 mL) and tetrahydro-2H-pyran-4-ol (0.20 mL, 2.1 mmol). The reaction mixture was heated to 100° C. for 1 h, heated to 130° C. for 2 h, and heated to 150° C. for 21 h. The reaction was diluted with EtOAc, and the organic phase was washed with saturated NaHCO3 (1×), brine (1×), dried over MgSO4, filtered, and concentrated. Purification by flash column chromatography on silica gel (60% to 100% EtOAc in hexanes) gave 5-methyl-2-(1-(3-(tetrahydro-2H-pyran-4-yloxy)pyrazin-2-yl)azetidin-3-yl)-1H-benzo[d]imidazole (0.061 g, 0.17 mmol, 49% yield) as a pale yellow foam. [M+1] 366. IC50 (uM) 0.2388.
