반응 단계
Using the same reaction conditions and work up as described in Example 1, step-3,1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 515 mg, 2.35 mmol) was refluxed with 3-bromo-4-dimethoxymethyl-pyridine (600 mg, 2.584 mmol), copper iodide (44.7 mg, 0.2312 mmol), N,N′-dimethyl-cyclohexane-1,2-diamine (80.8 mg, 0.7405 mmol), potassium phosphate (1.4 g, 7.046 mmol) and 1,4-dioxane (20 mL) at 110° C. for 12 hours to afford the crude product. The reaction was monitored by TLC (10% MeOH in chloroform). Purification by column chromatography on silica gel (2% methanol in chloroform) afforded 460 mg of the product (52.9% yield).
