Procedure
A solution of 6 g of the product of Step A, 60 ml of 10% sulphuric acid and 30 ml of tetrahydrofuran is heated at 50° C. for 12 hours, and then evaporated. The residue is taken up in ether, rendered basic with 20% sodium hydroxide solution, extracted with ethyl acetate, dried and evaporated, enabling the expected product to be isolated.
