Reaction Steps

A mixture of cesium carbonate (0.83 g, 2.56 mmol), 2-(azetidin-3-yl)-5-chloro-1H-benzo[d]imidazole dihydrochloride (as described in Preparation 5) (0.18 gg, 0.64 mmol), and 4-chloro-6-(tetrahydro-2H-pyran-4-yl)pyrimidine (0.13 g, 0.64 mmol) in DMA (1 mL) was heated to 70° C. for 18 h, then cooled to RT. The resulting suspension was partitioned between ethyl acetate and water, the layers were separated, and the organic layer was washed with water twice, brine once, dried over anhydrous magnesium sulfate, filtered, and concentrated in vacuo. The resulting oil was purified by silica gel chromatography to give 5-chloro-2-(1-(6-(tetrahydro-2H-pyran-4-yl)pyrimidin-4-yl)azetidin-3-yl)-1H-benzo[d]imidazole (0.11 g, 0.30 mmol, 47% yield) as a white solid. [M+1] 370. IC50 (uM) 1.283.
