Versuchsvorschrift

Using the same reaction conditions as in Example 79, 1-naphthalen-2-yl-imidazolidin-2-one (I-79b: 100 mg, 0.4711 mmol) was reacted with 5-bromo-nicotinic acid methyl ester (112 mg, 0.5182 mmol), 1,4-dioxane (10 mL), copper iodide (11 mg), trans-1,2-diamino cyclohexane (22 mg) and potassium phosphate (200 mg, 0.9422 mmol) to afford the crude product. Purification by column chromatography on silica gel (80% EtOAc in hexane) afforded 44 mg of the product (26.99% yield).
