Reaction Steps

A solution of Intermediate 23 (0.10 g) in ethanol (20 ml) was added to 10% palladium on carbon (0.20 g) and the mixture stirred under an atmosphere of hydrogen for 20 h. The mixture was filtered through ‘hyflo’ filter aid, washed with ethanol and the solvent removed in vacuo to give the title compound as a white solid (0.092 g).
