실험 절차

The bromide obtained in Step A is heated at reflux in 15 ml of acetic anhydide until completely dissolved. Cool and pour into 50 ml of cold water. Neutralise with a solution of sodium carbonate and extract twice with 10 ml of chloroform each time. Combine the organic phases, pass over a column of alumina and evaporate. Recrystallise the residue from ethyl acetate.
