Reaction Conditions

Reaction Steps

A solution of furan (23.8 g, 0.35 mol) in dry tetrahydrofuran (150 ml) was cooled to -15° C. A solution of n-butyl-lithium in hexane (150 ml, 2.2 M, 0.33 mol) was then added dropwise under nitrogen and the reaction mixture was then stirred for a further 21/2 hours at 0° C. The solution thus obtained was subsequently added over a period of about 1 hour under nitrogen to a solution of 1,4-dibromobutane (150 g, 0.7 mol) in dry tetrahydrofuran (225 ml) at -25° C.
