1,2-Diaminocyclohexane, trans- → 1-(3-Acetyl-4-fluoro-phenyl)-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: 500 mg, 2.8248 mmol) was reacted with 1-(5-bromo-2-fluoro-phenyl)-ethanone (610 mg, 2.8248 mmol), 1,4-dioxane (15 mL), copper iodide (53.81 mg, 0.28248 mmol), trans-1,2-diamino cyclohexane (97.03 mg, 0.8474 mmol) and potassium phosphate (1.798 g, 8.474 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 170 mg of 1-(3-acetyl-4-fluoro-phenyl)-3-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (19.31% yield).
