Morpholine → 4-(2-Fluoro-4-nitrobenzyl)morpholine

참여 물질

반응 단계

2-Fluoro-4-nitrotoluene (1.55 g, 10 mmol), N-bromosuccinimide (1.82 g, 10 mmol), and benzoyl peroxide (0.1 g, 0.4 mmol) were dissolved in CCl4 (50 mL). The mixture was heated at reflux, and irradiated with light (100 W bulb) for 4 hours. The reaction mixture was then filtered and concentrated. The residue was dissolved in THF (50 mL). Morpholine (1.91 g, 22 mmol) was added to it. The mixture was stirred at ambient temperature for 1 hour and then filtered. The filtrate was evaporated. The bright orange residue was purified by column chromatography eluted with hexane:ethyl acetate, 10:1 to provide 4-(2-fluoro-4-nitrobenzyl)morpholine (1.32 g, 5.5 mmol, yield 55%).
