実験手順

4-(1-Benzyl-pyrrolidin-3-yl)-2-methoxy-phenylamine (220 mg, 0.78 mmol) and 4-isopropylphenylsulfonyl chloride (170 mg, 0.78 mmol) were dissolved in tetrahydrofuran (20 ml). Triethylamine (0.32 ml, 2.34 mmol) was added and the reaction mixture stirred over night at room temperature (10% conversion) and subsequently refluxed for 4 h (70% conversion). One small portion of 4-isopropylphenylsulfonyl chloride and triethylamine were added and the reaction mixture was stirred 15 min at 150° C. in the microwave (CEM). The solvent was evaporated under reduced pressure, the residue treated with ethyl acetate (50 ml) and extracted twice with slightly acidic water. The organic layer was dried over magnesium sulfate, filtered, and the solvent evaporated under reduced pressure to give an oil (470 mg). The crude product was purified via silica gel chromatography with cyclohexane/ethyl acetate (gradient 0-100%). Fractions containing the product were combined the solvent evaporated to yield an oil (143 mg, 40%).
