The alkene mixture of step (b) (29 g) was dissolved in ethanol (300 ml) and hydrogenated in the presence of 5% palladium on charcoal (1.0 g) at 45 psi; until hydrogen uptake had ceased. The catalyst was filtered off through a supercel filter aid and the filtrate was evaporated to give the desired compound 29.2 g (99.4%). NMR and MS analysis were correct for the required compound.
