実験手順

Perfluorophenyl 3-(1-(4-methoxy-2,6-dimethylphenylsulfonyl)piperidin-2-yl)propane-1-sulfonate (40 mg, 0.07 mmol) and 1-(1-methyl-4-piperidinyl)piperazine (25 mg, 0.14 mmol) were dissolved in tetrahydrofuran (10 ml), 1,8-diazabicyclo[5.4.0]undec-7-ene (0.03 ml, 0.21 mmol) was added under an inert gas and the mixture was refluxed for 1 h and stirred at room temperature for 15 h. Methylene chloride and saturated sodium bicarbonate solution (10 ml of each) were added, the phases were separated and the aqueous phases were extracted with methylene chloride (20 ml). The combined organic phases were dried over sodium sulfate and concentrated in vacuo. The crude product was purified by column chromatography (silica gel) with ethyl acetate/methanol/ammonia (25 aq) (200:100:1). Yield: 18 mg (45%). MS, m/z=571.3 [MH]+
