Potassium Carbonate → 1-Benzothiazol-5-yl-3-pyridin-3-ylimidazolidin-2-one

Participants

Reaction Steps

Using the same reaction conditions as in Example 1, 1-pyridin-3-yl-imidazolidin-2-one (I-1b: 93.67 mg, 0.5747 mmol) was reacted with 5-iodo-benzothiazole (150 mg, 0.5747 mmol), 1,4-dioxane (5 mL), copper iodide (10.9 mg, 0.05747 mmol), trans-1,2-diamino cyclohexane (19.65 mg, 0.1724 mmol) and potassium carbonate (159 mg, 1.1494 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform) afforded 105 mg of the product (61.76% yield).
