To the above nitro compound (Example 1, Part C; 0.5 g, 1.11 mmol) was added PtO2 (Adam's) catalyst (0.025 g) and EtOH (absolute, 40 mL). The mixture was rapidly stirred under a hydrogen atmosphere (balloon) for 1.5 h and then the catalyst removed by filtering over a pad of diatomaceous earth. The filtrate was concentrated under reduced pressure, yielding 460 mg (99%) of the desired product.
