実験手順

119 mg (0.39 mmol) of the compound from Example 5A and 107 mg (0.77 mmol) of potassium carbonate were dissolved in 5 ml of acetonitrile, and 65 mg (0.39 mmol) of 2-chloro-5-(chloromethyl)thiophene were added. The mixture was stirred under reflux for 2 h. After cooling to RT, 10 ml of water were added and the mixture was extracted three times with in each case 10 ml of ethyl acetate. The combined organic phases were washed with 10 ml of saturated sodium chloride solution, dried over sodium sulfate, filtered and concentrated under reduced pressure. The crude product was purified by chromatography on silica gel (mobile phase: cyclohexane/ethyl acetate 10:1→8:1→5:1→1:1). This gave 114 mg (65% of theory) of the target compound.
