Procedure

2-({1-[1-(4-Chlorophenyl)cyclobutyl]-3,4-dihydroisoquinolin-6-yl}oxy)ethanamine (0.40 g, 0.90 mmol) was dissolved in dichloromethane (8 mL) and propane-1-sulfonyl chloride (0.169 g, 1.18 mmol) and N,N-dimethylpyridin-4-amine (0.152 g, 1.24 mmol) were added. The reaction mixture was stirred at room temperature over night. Water was added and the aqueous phase was extracted several time with dichloromethane. The combined organic layers were dried (Na2SO4) and concentrated in vacuo. The crude product was purified by flash chromatography (silica, dichloromethane:methanol=99:1). Yield: 0.35 g (0.68 mmol, 76%, colorless oil).
