실험 절차

A mixture of 4-(4-chloro-6-methylquinolin-2-yl)-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,1-dioxide (150 mg, 0.40 mmol, prepared in analogy to the one in Example 2-1), hydrogen iodide salt of 4,5-dihydro-1H-imidazol-2-amine (110 mg, 0.515 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (25 mg, 0.043 mmol), tris(dibenzylideneacetone)dipalladium(0) (35 mg, 0.038 mmol), cesium carbonate (525 mg, 1.6 mmol) and 1,4-dioxane (3 mL) was heated with stirring in a 5 mL of microwave process vial for 2 hours at 120° C. under microwave irradiation. The resulting mixture was filtered and washed with ethyl acetate. The filtrate was washed with brine, dried over sodium sulfate, and concentrated in vacuo. The residue was purified by preparative HPLC to afford the product as a solid. MS obsd.
