Reaction Steps

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 100 mg, 0.5643 mmol) was reacted with 2-bromo-4-chloro-thieno[3,2-c]pyridine (141.3 mg, 0.5643 mmol), 1,4-dioxane (20 mL), copper iodide (10.75 mg, 0.05643 mmol), trans-1,2-diamino cyclohexane (19.38 mg, 0.1693 mmol) and potassium phosphate (299 mg, 1.4108 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 43 mg of the product (22.16% yield).
