Reaction Steps
A stirred mixture of 5-(bromo-m-tolyl-acetyl)-1-isopropyl-3-methyl-1,3-dihydro-benzoimidazol-2-one (prepared as described in example 142, 0.5 gm, 1.25 mmol), pyrazine-2-carboxamidine hydrochloride (0.395 gm, 2,49 mmol) cesium carbonate (1.22 gm, 3.74 mmol) and DMF (4.0 mL) was heated to 60° C. After 1 hour, the reaction was determined to be complete by LCMS. The reaction was cooled to room temperature and diluted with water (40 mL). After stirring for 1 hour, the crude suspension was filtered and the solids were purified by flash chromatography (diethyl ether, followed by ethyl acetate) to afford 40 mg of the title compound as a light tan solid. MS (M+1)=425.1
