Participants

Reaction Steps

Phosphorus tribromide (0.35 mmol) was added to a solution of 3,4-methylenedioxy benzyl alcohol (1 mmol) in 10 ml of carbon tetrachloride at room temperature. The reaction mixture was refluxed for 4 hrs., cooled to room temperature and washed with sodium carbonate solution (10 ml). The organic layer was dried and concentrated under reduced pressure to give the required product which was used as such for the next step.
