실험 절차

A mixture of 2-methyloxirane-2-carboxylic acid (3-methyl-4-nitrophenyl)amide (0.2 g, 0.85 mmol), 4-fluoroaniline (0.18 g, 1.7 mmol) and sodium perchlorate (0.21 g, 1.7 mmol) in 2 ml of acetonitrile was boiled under reflux for 6 hours. After a workup of the reaction mixture, the crude product was purified by flash chromatography (dichloromethane-1% methanol). 1H NMR (400 MHz, DMSO-d6): 1.41 (3H, s), 2.51 (3H, s), 3.10 (1H, dd, J=12.7 Hz, J=4.6 Hz), 3.41 (1H, dd, J=12.7 Hz, J=7.7 Hz), 5.26 (1H, m), 6.02 (1H, s), 6.62-6.66 (2H, m), 6.84-6.89 (2H, m), 7.79-7.83 (2H, m), 8.02 (1H, d, J=8.9 Hz), 9.99 (1H, s).
