Procedure

A flask containing 4-(4-chloro-6-methylquinolin-2-yl)-2,3,4,5-tetrahydro-1,4-benzothiazepine 1,1-dioxide (250 mg, 0.67 mmol), thietane-3,3-diyldimethanamine (266 mg, 2.01 mmol), tris(dibenzylideneacetone)dipalladium(0) (61.8 mg, 0.067 mmol), 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (42 mg, 0.067 mmol), sodium tert-butoxide (160 mg, 1.66 mmol) and toluene (15 mL) was evacuated and then filled with nitrogen (balloon). After being stirred at 110° C. overnight, the resulting mixture was diluted with water (15 mL) and extracted with ethyl acetate (15 mL×4). The combined organic layers were dried over sodium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography and preparative HPLC to afford 63 mg of the product as a white solid (yield was 20%). MS obsd.
