Using the same reaction conditions and work up as described in Example 1, step -3,3-bromo-4-pyrrolidin-1-ylmethyl-pyridine (I-176a: 290 mg, 1.205 mmol) was refluxed with 1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 220 mg, 1.004 mmol), copper iodide (19 mg, 0.1004 mmol), N,N′-Dimethyl-cyclohexane-1,2-diamine (42.7 mg, 0.301 mmol), potassium phosphate (640 mg, 3.012 mmol) and 1,4-dioxane (15 mL) at 120° C. for 12 hours to afford the crude product. The reaction was monitored by TLC (5% MeOH in DCM). Purification by column chromatography on silica gel (5% MeOH in chloroform) followed by preparative HPLC afforded 72 mg of the product (18.9% yield).
