実験手順
A solution of (2-chloro-6-methylquinolin-4-yl)acetic acid (118 mg, 0.5 mmol) and 2,3,4,5-tetrahydro-1,4-benzothiazepine (247 mg, 1.5 mmol) in n-butanol (0.2 mL) was heated with stirring in a sealed 0.5 mL of microwave process vial for 2 hours at 160° C. After being cooled to room temperature, the reaction mixture was diluted with dichloromethane (50 mL), washed with a saturated aqueous solution of sodium carbonate (50 mL) and brine (50 mL), dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (eluting with 20-30% ethyl acetate in petroleum ether) to afford 100 mg of the desired product (yield was 62%). MS (ESI+) [(M+H)+] 321.
