Reaction Steps

1-Benzothiazol-6-yl-imidazolidin-2-one (I-84b: 150 mg, 0.6904 mmol) was reacted with 2-bromo-pyridine (99 mL, 1.0356 mmol), 1,4-dioxane (10 mL), copper iodide (16 mg), trans-1,2-diamino cyclohexane (32 mg) and potassium phosphate (440 mg, 2.0713 mmol) to afford the crude product. Purification by column chromatography on silica gel (10% ethylacetate in hexane), followed by preparative HPLC afforded 37 mg of the product (18.13% yield).
