In a 100 ml round-bottomed flask, 0.003 mol of methyl 4′-hydroxy[1,1′-biphenyl]-4-carboxylate and 0.003 mol of the compound obtained in Step A are dissolved in a mixture of 3 ml of dimethyl sulphoxide and 20 ml of butanone. 0.009 mol of potassium carbonate and one potassium iodide crystal are added and then the mixture is heated at reflux for 12 hours. The reaction mixture is then cooled and poured into 100 ml of water. The precipitate that forms is suctioned off and recrystallised to yield the title product.
