반응 단계

To a solution of pentan-3-one oxime (6.00 g) in dimethylformamide (30 ml) was added sodium hydride (60% oil suspension, 2.37 g) under ice cooling. After 15 minutes, to the above mixture was added dropwise 1-fluoro-2-nitrobenzene (5.98 g) in dimethylformamide (30 ml). The mixture was stirred for 3 hours at ambient temperature and poured into a mixture of ice and water. The separated oil was extracted with diethyl ether. The organic layer was washed with water, dried over sodium sulfate and evaporated in vacuo to give pentan-3-one O-(2-nitrophenyl)oxime (10.51 g) as a brown oil.
