実験手順
4-((1R,2S)-2-{2-{2-fluoro-4-(methylsulfonyl)phenoxy]ethyl}cyclopropyl)piperidine (Step C, Example 111; 150 mg, 0.428 mmol) and potassium carbonate (244 mg, 1.77 mmol) were stirred in chloroform (7 mL). Cyanogen bromide (61 mg, 0.58 mmol) was added. The mixture was stirred at RT for 15 min and refluxed overnight. The mixture was cooled to RT, mixed with silica gel (5 g), and concentrated to dryness under reduced pressure. The residue was loaded on a silica gel column (15 g of silica gel) and eluted with dichloromethane/methanol (97.5:2.5, 1 L to provide the title compound as an white solid. MS (Multimode) m/z 367 [M+H]+.
