Reaction Steps

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 150 mg, 0.84650 mmol) was reacted with 2-chloro-benzooxazole (96 mL, 0.84650 mmol), 1,4-dioxane (50 mL), copper iodide (16 mg, 0.084650 mmol), trans-1,2-diamino cyclohexane (29 mg, 0.2539 mmol) and potassium carbonate (468 mg, 3.3860 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in DCM) afforded 40 mg of the product (16% yield).
