N-[2-({1-[1-(4-Fluorophenyl)cyclobutyl]-1,2,3,4-tetrahydroisoquinolin-7-yl}oxy)ethyl]propane-1-sulfonamide (92 mg, 0.206 mmol, cf. example 65) was dissolved in tetrahydrofuran (1 mL) under an atmosphere of nitrogen. Tert-butyl nitrite (32 mg, 0.309 mmol) were added and the reaction mixture was stirred under reflux for 3 h. After that time additional tert-butyl nitrite (32 mg, 0.309 mmol) was added and stirring under reflux was continued for 2 h. The solvent was evaporated in vacuo and the crude product was purified by flash chromatography (silica, dichloromethane then dichloromethane:methanol=100:1). Yield: 56 mg (0.118 mmol, 57%).
