Reaction Steps

A mixture of the product of Example 278A (171 mg, 0.38 mmol) and palladium (10%) on carbon (489 mg, 0.46 mmol of palladium) in methanol was flushed with hydrogen, and stirred under a hydrogen balloon for 5 hours. The mixture was then filtered through Celite, rinsed, with ethyl acetate, and concentrated in vacuo. The residue was purified by column chromatography (5% methanol-ethyl acetate) to give the title compound (97 mg, 56%).
