Reaction Steps
Pyrrolidine ((983 μl, 12.0 mmol, commercially available product) was added at 0° C. to a N,N-dimethylformamide (DMF; 4 ml) solution of 1-fluoro-2-nitro-4-(trifluoromethyl)benzene (1.02 g, 4.89 mmol, commercially available product). The resulting mixture was warmed to room temperature and stirred for 4.5 hours. Water was added to the mixture, and the resulting mixture was extracted three times with ethyl acetate. The obtained organic layer was washed with a saturated sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (50 g, hexane/ethyl acetate=5/1). Thus, 1-[2-nitro-4-(trifluoromethyl)phenyl]pyrrolidine (1.26 g, 99.3%) was yielded as an orange-colored solid.
