Reaction Steps

6'-Hydroxyspiro-(9H-fluorene-9,3'-piperidine)-2'-one (2.7 g) was dissolved in isopropylamine (350 ml) and 10% palladium on charcoal (0.3 g) was added and the vessel pressurised to 90 p.s.i. with hydrogen. The reaction mixture was then heated at 40° C. for 16 hours and then allowed to cool to room temperature. The catalyst was removed by filtration and the isopropylamine evaporated under reduced pressure. The resulting residue was dissolved in dichloromethane (20 ml) washed with water (2×50 ml), dried with anhydrous sodium sulphate and evaporated to dryness under reduced pressure. The residue was triturated with hexane to give the title compound as white crystals, the identity of which was confirmed by thin layer chromatographic comparison with an authentic sample (silica gel, ethylacetate:methanol 80:20 v/v).
