الإجراء التجريبي

A solution of 1.0 g 1,1,2-tribromo-2-(7-hydroxyheptyl)cyclopropane (2.5 mmol) in 25 ml of ether was treated at −78° C. with 7.2 ml of methyllithium (1.4 M, 10 mmol). After 5 minutes, the reaction mixture was warmed to 0° C. and held at this temperature. The reaction was quenched with saturated ammonium chloride. The reaction mixture was washed with water and brine, dried over magnesium sulfate, filtered and stripped to give 240 mg of 1-(7-hydroxyheptyl)-cyclopropene (90% purity).
