How is 1-(Allyloxy)butane (CAS: 3739-64-8) typically synthesized?

1-(Allyloxy)butane (CAS: 3739-64-8) is typically synthesized through the allylation of butanol using an allyl halide in the presence of a base. The reaction involves the nucleophilic attack of the alcohol moiety of butanol on the allyl halide, followed by proton elimination to form the desired product. The reaction is often carried out in a polar aprotic solvent like THF with a base such as potassium tert-butoxide.
