실험 절차

A mixture of 4-chlorophenyl phenyl sulfone (10.1 g, 40.0 mmol), hydrazine monohydrate (30 mL), and triethylamine (4 drops) in ethylene glycol (20 mL) is heated at 150° for 15 hr. Upon cooling, the mixture is diluted with H2O and filtered. The residual solid is washed with H2O until the washings are neural (pH=6). This material is then triturated with methylene chloride and dried under reduced pressure at 50° to give the title compound, IR (drift) 3282, 1586, 1514, 1306, 1291, 1158, 1145, 1104, 996, 813, 756, 730, 717, 688 and 678 cm−1; NMR (300 MHz, CDCl3) 7.70–7.85, 7.45–7.65, 6.79 and 4.22 δ; MS (EI) m/z 248 (M+), 125, 123, 108, 107, 90, 80, 77, 63 and 51.
