Procedure

In an autoclave, a solution of 75.1 g (0.27 mole) of ethyl 4-[(2-hydroxyiminocyclopentyl)methyl]benzeneacetate in 800 ml of anhydrous ethanol saturated with NH3 is combined with about 37.5 g of Raney Nickel in water. The mixture is stirred under 80 atmospheres of hydrogen, at 80° C. during 4 hours. After cooling, the catalyst is filtered and rinsed with ethanol. The concentrated filtrate under reduced pressure, gives 69.3 g (yield=98.3%) of an orange oil which crystallizes but which is used without any other purification.
