Reaction Steps

A slurry of the product from Example 64A (0.19 g, 0.469 mmol) and 10% Pd/C (0.025 g) in acetic acid (3 ml) was placed under a hydrogen atmosphere with stirring for 2 hr at room temperature. The slurry was filtered and the solvent removed under vacuum leaving a brown solid as an acetate salt of the title compound (0.21 g, 91%).
