1,2-Diaminocyclohexane, trans- → 1-Benzothiazol-6-yl-3-(4-dimethoxymethyl-pyridin-3-yl)-imidazolidin-2-one

Participants

Reaction Steps

Using the same reaction conditions as in Example 14, 1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 590 mg, 2.7 mmol) was reacted with 3-bromo-4-dimethoxymethyl-pyridine (I-149a: 690 mg, 2.97 mmol), 1,4-dioxane (50 mL), copper iodide (51.46 mg, 0.27 mmol), trans-1,2-diamino cyclohexane (93 mg, 0.81 mmol) and potassium phosphate (1.72 g, 8.1 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in CHCl3) afforded 510 mg of the product (51.2% yield).
