Reaction Steps

1-Benzothiazol-6-yl-imidazolidin-2-one (I-84b: 150 mg, 0.6849 mmol) was reacted with 5-bromo-1-methyl-1H-imidazole (121.3 mg, 0.753 mmol), 1,4-dioxane (5 mL), copper iodide (12.99 mg, 0.0684 mmol), trans N,N′-dimethyl-cyclohexane-1,2-diamine (29.176 mg, 0.205 mmol) and potassium phosphate (435.01 mg, 2.05 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 85 mg of the product (41.64% yield).
