실험 절차
A mixture of 4-chloro-3-nitrophenyl methyl sulfone (4 g, 17 mmole) and N,N-dimethylethylenediamine (3.3 g, 37 mmole) in DMSO (20 ml) was stored at 75° C. for 1 hour and poured into crushed ice. The yellow solid precipitate was collected by filtration and was dissolved in ethyl acetate. The organic phase was washed with water-brine mixture twice and brine, dried over sodium sulfate, and evaporated under reduced pressure to give the sulfone (22) (3.8 g, 78%) as a yellow solid. A pure sample (m.p. 130°-131° C.) was obtained by recrystallization from ethyl acetate.
