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, 0.00084 mol) was reacted with 3-bromo-1-(toluene-4-sulfonyl)-1H-indole (292 mg, 0.00084 mol), 1,4-dioxane (20 mL), copper iodide (0.015 g, 0.000084 mol), trans-1,2-diamino cyclohexane (0.028 g, 0.00025 mol) and potassium phosphate (356 mg, 0.00168 mol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3), followed by preparative HPLC afforded 110 mg of 1-(4-Methyl-pyridin-3-yl)-3-[1-(toluene-4-sulfonyl)-1H-indol-3-yl]-imidazolidin-2-one (33.66% yield).
