2-({1-[1-(4-Chlorophenyl)cyclobutyl]-4,4-dimethyl-3,4-dihydroisoquinolin-7-yl}oxy)ethanamine (145 mg, 0.38 mmol, cf. example 67) was dissolved in dry dichloromethane (8 mL). Triethylamine (60 μL, 0.45 mmol). The solution was cooled to 0-5° C. and diethylsulfamoyl chloride (71.5 mg, 0.42 mmol) was added. The reaction mixture was stirred at room temperature over night. The reaction mixture was diluted with dichloromethane (20 mL) and washed with a 1:1 mixture of water and saturated ammonium chloride solution (20 mL). The organic layer was dried (MgSO4) and the solvent was evaporated in vacuo. The crude product was purified by flash chromatography (silica, dichloromethane then dichloromethane:ethyl acetate=180:5). Yield: 96 mg (0.19 mmol, 48.9%).
