A mixture of cesium carbonate (0.82 g, 2.52 mmol), 2-(azetidin-3-yl)-5-chloro-1H-benzo[d]imidazole dihydrochloride (as described in Preparation 5) (0.18 gg, 0.63 mmol), and 2-chloro-3-(tetrahydro-2H-pyran-4-yl)pyrazine (0.13 g, 0.63 mmol) in DMA (1 mL) was heated to 80° C. for 20 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 (2×), brine, 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-(3-(tetrahydro-2H-pyran-4-yl)pyrazin-2-yl)azetidin-3-yl)-1H-benzo[d]imidazole as a white solid. [M+1] 370. IC50 (uM) 1.157.
