Versuchsvorschrift

METHOD A The product from Example 15 (1.77 g, 0.007 mole) was treated dropwise at 0° C. with concentrated sulphuric acid (2.3 ml). The resulting green gum was allowed to stand overnight at room temperature and was then treated with 25 ml of crushed ice and after thorough mixing, 50 ml of water. The solution was neutralised with excess ammonia and the solution shaken with ether (2×50 ml). The ether layers were washed, and dried (MgSO4) and evaporated to give 360 mg of the title compound as a 50:50 mixture of diastereoisomers.
