YieldReaction ConditionsOperation in experiment
162 mg (0.92 mmol,11%) With hydrogen azide; sulfuric acid; In chloroform; water; Step A: 7-fluoro-2,3,4,5-tetrahydro-1H-1-benzazepin-2-one Sodium azide 1.1 g (16.92 mmol) was added to a mixture of 6.0 mL of chloroform and 1.1 mL of water at 0° C. Concentrated sulfuric acid (0.44 mL) was added dropwise and the mixture stirred at 0° C. for two hours then filtered. The chloroform layer containing hydrazoic acid was added to a solution of 1.3 g (7.92 mmol) of <strong>[703-67-3]6-fluoro-1-tetralone</strong> (prepared by the method of Allinger and Jones, J. Org. Chem., 27, 70-76 (1962)) in 4.8 mL of chloroform. Additional sulfuric acid (2.16 mL) was added dropwise with stirring while maintaining the temperature below 40° C. The mixture was stirred at 40° C. for two hours then at room temperature for 16 hours. The mixture was transferred to a separatory funnel and the layers were separated. The aqueous layer was added to ice; the resulting precipitate was extracted with methylene chloride (5*). The combined extracts were washed with brine, dried over magnesium sulfate and filtered through a silica plug. Solvents were removed under vacuum to afford 162 mg (0.92 mmol,11percent) of the product. 1 H NMR (300 MHz, CDCl3): 2.21 (m,2H), 2.32 (t,7 Hz,2H), 2.77 (t,7 Hz,2H), 6.93 (m,3H), 7.8 (br s,1H). FAB-MS: calculated for C10 H10 FNO 179; found 180 (M+H,100percent).
