Reaction Steps
The compound from Step 2 is suspended in dry ethanol and O-trimethylsilyl hydroxylamine (10 eq.) is added. The mixture is refluxed for 2 h, evaporated and the crude mixture purified by RP HPLC on a Phenominex column (250×20 mm) using a gradient of acetonitrile in water from 0 to 30% over 30 minutes at 10 mL/minute to yield the title compound.
