Methanol → Methyl 6,8-dichlorooctanoate

Participants

Reaction Steps

9 g (0.042 moles) of (+)-6,8-dichlorooctanoic acid are dissolved in 120 ml of methanol containing 0.45 ml of aqueous hydrochloric acid at 37% by weight. The solution is refluxed for two hours, the solvent is evaporated at reduced pressure, 17 ml of toluene are added and the obtained solution is washed twice with 10 ml of water. The toluene phase is concentrated under vacuum, thus obtaining 9.4 g of methyl (+)-6,8-dichlorooctanoate (yield=98.6%).
