A mixture of 4-(4-chloro-6-methylquinolin-2-yl)-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,1-dioxide (682 mg, 1.83 mmol, prepared in analogy to 4-(4-chloro-6-(trifluoromethoxy)quinolin-2-yl)-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,1-dioxide in Example 17-1 by using 2,4-dichloro-6-methylquinoline and 2,3,4,5-tetrahydro-1,4-benzothiazepine 1,2-dioxide) in 1,4-dioxane (5 mL) was added tert-butyl 2-(aminomethyl)morpholine-4-carboxylate (395 mg, 1.83 mmol), 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (146 mg, 0.18 mmol), 1,1′-bis(diphenylphosphino)ferrocene (100 mg, 0.18 mmol) and sodium tert-butoxide (350 mg, 3.66 mmol) under Argon protection. The mixture was heated with stirring under microwave irridiation at 120° C. for 1.5 hours. The reaction mixture was concentrated in vacuo and the residue was purified by preparative HPLC to give 100 mg of the desired product (yield was 10%).
