Versuchsvorschrift

cis-N-(2-{[7-(2,4-Dioxo-3-azabicyclo[3.1.0]hex-3-yl)-8-(2-fluorobenzyl)-5,6,7,8-tetrahydronaphthalen-2-yl]oxy}ethyl)-1-methyl-1H-imidazole-4-sulfonamide (38 mg, 0.069 mmol) was dissolved in tetrahydrofuran (2 mL) and borane tetrahydrofuran complex was added (1 N, 0.4 mL, 0.4 mmol). The reaction mixture was heated to 50° C. for 3.5 h. After cooling to room temperature methanol (0.2 mL) was added dropwise and stirring was continued for 30 min. The reaction mixture was diluted with dichloromethane, washed with saturated sodium chloride solution and dried (magnesium sulfate). The solvent was evaporated in vacuo and the crude product was purified by flash chromatography (silica, dichloromethane/methanol). Yield: 4 mg (7.6 μmol, 11%, colorless oil).
