1,2-Diaminocyclohexane, trans- → 1-(5-Difluoromethyl-thiophen-3-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: 150 mg, 0.8474 mmol) was reacted with 4-bromo-2-difluoromethyl-thiophene (179.6 mg, 0.8474 mmol), 1.4-dioxane (5 mL), copper iodide (16.14 mg, 0.08474 mmol), trans-1,2-diamino cyclohexane (29.1 mg, 0.2542 mmol) and potassium phosphate (539.59 mg, 2.542 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 22 mg of the product (8.5% yield).
