Reaction Steps

0.055 mol of the compound obtained in Step B and 100 g of polyphosphoric acid are introduced into a 500 ml round-bottomed flask. The reaction mixture is heated at 60° C. for 3 hours and is then cooled and poured into water. Extraction with ethyl ether is carried out; the organic phase is washed with water, dried over MgSO4 and evaporated under reduced pressure. The residue obtained is purified by chromatography on silica gel. Yellow oil
