실험 절차

2.1 ml abs. pyridine and 21.62 g thionyl chloride (13.3 ml,. 0.18 mol) is added to 10.13 9 2-(2-nitrophenyl)ethanol (60 mmol) in 36 ml abs. toluene. After 2 h reflux, this is cooled and poured onto ice. The ice water is mixed with 50 ml chloroform and extracted 2× each with 50 ml chloroform. The combined organic phases are neutralized 2× each with 100 ml saturated bicarbonate solution. After drying with Na2SO4, this is filtered and rotary evaporated. After distillation under high-vacuum, 9.7 9 (50 mmol,. 87%) 2-(2-nitrophenyl)ethyl chloride is obtained as a yellow oil with a boiling point of 66 to 67° C. (0.001 mbar).
