Reaction Steps

To a solution of the product from Example 6 (3.0 g) in ethanol, was added 10% palladium on charcoal (300 mg). The reaction mixture was treated with H2 at atmospheric pressure until uptake ceased. On completion, the reaction was filtered and the solvent was removed from the filtrate in vacuo to give a green oil. Traces of remaining catalyst were removed by filtration to give a yellow oil. The oil was precipitated from ethyl acetate/40°-60° petroleum ether to afford the title compound as a white solid, mp 147°-148°C.
