실험 절차

A mixture solution of 4-(4-chloro-6-methylquinolin-2-yl)-8-methoxy-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,1-dioxide (60.0 mg, 0.15 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 8-methoxy-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,2-dioxide), tert-butyl carbamate (45.0 mg, 0.37 mmol), 1,1′-bis(diphenylphosphino)ferrocene (11.2 mg, 0.02 mmol), 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (15.0 mg, 0.02 mmol), and sodium tert-butoxide (75.0 mg, 0.72 mmol) in 1,4-dioxane (2.0 mL) was heated with stirring at 120° C. for 2 hours. After being cooled to room temperature, the reaction mixture was extracted with ethyl acetate (100 mL), washed with brine (50 mL×2), dried over anhydrous sodium sulfate and concentrated in vacuo to afford 59.9 mg of the crude product as yellow oil. MS obsd. (ESI+) [(M+H)+] 484.
