Procedure

A solution of the product of part (ii) (0.50 g) in methanol (50 ml) was hydrogenated at room temperature and 3.5 bar in the presence of 5% palladium on carbon (50 mg) until the required amount of hydrogen had been absorbed. The catalyst was filtered off and the filtrate was evaporated to give the title compound (0.45 g) as a gum which was used without further purification.
