実験手順
A solution of the product from Example 201B (203 mg, 0.611 mmol) in methanol (20 mL) was added to Raney®-nickel 2800, water slurry (2030 mg, 34.6 mmol) in a 50 mL pressure bottle. The mixture was stirred at ambient temperature for 16 hours under hydrogen (30 psi). The mixture was filtered and concentrated in vacuo to give the title compound. MS (ESI) m/z 275 (M+H)+.
