1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 240 mg, 1.0945 mmol) was reacted with 5-chloro-imidazo[1,2-a]pyrazine (I-186a: 202 mg, 1.3135 mmol), 1,4-dioxane (3 mL), copper iodide (24 mg), trans N,N′-dimethyl-cyclohexane-1,2-diamine (48 mg) and potassium phosphate (581 mg, 2.7364 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3), followed by preparative HPLC afforded 13 mg of the product (3.53% yield).
