Potassium Carbonate → 1-(3-Methyl-benzofuran-5-yl)-3-(4-methyl-pyridin-3-yl)-imidazolidin-2-one

Participants

Reaction Steps

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 105 mg, 0.8465 mol) was reacted with 5-bromo-3-methyl-benzofuran (197 mg, 0.9311 mmol), 1,4-dioxane (10 mL), copper iodide (20 mg), trans-1,2-diamino cyclohexane (40 mg) and potassium carbonate (359 mg, 1.6930 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in chloroform) afforded 80 mg of the product (30.76% yield).
