Procedure

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), benzene-1,3-diamine (86 mg, 0.80 mmol), palladium acetate (18 mg, 0.04 mmol), 2,2′-bis(diphenylphosphino)-1,1′-binaphthalene (50 mg, 0.04 mmol), potassium phosphate (169.6 mg, 0.8 mmol) and 1,4-dioxane (3 mL) in a 2-5 mL of process vial was heated at 140° C. under microwave irradiation for 1.5 hours. After being cooled to room temperature, the 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 pure product as a solid. MS obsd.
