Reaction Steps

To a 100 mL round-bottomed flask was added the product from Example 35 Part A (132 mg, 0.219 mmol), 10% palladium on carbon (20 mg, 0.019 mmol) and methanol (10 mL). The mixture was hydrogenated for 24 hours, filtered and concentrated in vacuo to give crude product which was purified by silica gel flash chromatography eluting with ethyl acetate/hexane (10% to 20%) to give the title compound.
