Reaction Steps
The product of Example 304H (0.059 g, 0.11 mmol) in tetrahydrofuran (4 mL) was reacted with platinum oxide (50 mg) under hydrogen atmosphere at 25° C. for 20 hours. The catalyst was filtered off and the filtrate evaporated to give the title compound (0.048 g, 100%). MS (ESI−) m/z 425 (M−H)−.
