prop-2-enyl 4-bromobutanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Allyl 4-bromobutyrate (19.7 g) was treated with potassium thioacetate (10.9 g) in dimethyl formamide (100 ml) at 20° C. for 2 hours. Water (500 ml) was added and the mixture extracted with diethyl ether. The ethereal solution was washed with dilute aq. HCl, brine, dried (MgSO4) and evaporated to give the title compound as an oil (18.6 g, 97%) the mixture extracted with diethyl ether The ethereal solution was washed with dilute aq. HCl, brine dried (MgSO4) evaporated

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4-Bromobutryl chloride (18.6 g) was treated with allyl alcohol (5.8 g) in the presence of pyridine (8 g) in dry dichloromethane at 0° C. for 0.5 hours. The solution was treated with aqueous HCl and warmed to room temperature. The organic layer was separated, washed with saturated aqueous brine, dried (MgSO4) and evaporated to give the title compound as a colourless oil, 19.7 g, 95% yield The organic layer was separated washed with saturated aqueous brine dried (MgSO4) evaporated
