실험 절차

1-(3-Bromophenyl)cyclopropanecarbonitrile (Reference compound 25-1, 5.0 g, 23 mmol) and ethylene glycol (20 mL) were added to a solution of potassium hydroxide (3.7 g, 66 mmol) in water (20 mL). The mixture was stirred at 140° C. for 4 hours. The reaction mixture was poured into a solution mixture of ice-water mL) and 6 N hydrochloric acid (50 mL). The precipitated solid was separated by filtration and dried under reduced pressure to give the title reference compound (4.7 q) as a brown solid (yield 87%).
