Procedure
After being solubilised in ethanol (510 ml), the unsaturated compound obtained in Step A (10 g, 3.05.10−2 mol) is hydrogenated in the presence of Raney nickel at ambient temperature with vigorous stirring. The reaction is monitored by TLC and GPC after 4 hours' hydrogenation. After it has been established that the starting material has disappeared, the catalyst is filtered off over Celite and the ethanol is evaporated off under reduced pressure. The title product is obtained in the form of a colourless oil.
