Conditions

Temperature: 80 °C

Procedure

Raney Nickel (1 g) was added to a solution of the product of (a) (1.2 g, 5 mmol) in absolute ethanol (120 ml) and the reactants heated at 80° C. in an autoclave for 18 hours. After cooling to ambient temperature, further Raney Nickel (1 g) was added to the reaction mixture and the reactants heated at 80° C. in an autoclave for an additional 6 hours. The reaction mixture was then filtered through Arbocel and the filtrate evaporated to dryness. The residue was flash chromatographed (Merck 60 Kieselgel--ethyl acetate:hexane:diethylamine, 25:75:2) to give the title product as a gum which solidified on standing (0.36 g, 35%), and was used directly in Preparation 19.
