Reaction Steps

Compound 13 (10 mg, 0.018 mmol) and hydroxylamine hydrochloride (50 eqv., 0.92 mmol, 64 mg) were dissolved in 2 mL of EtOH. Pyridine (0.1 mL) was added and the mixture was stirred at 45° C. for 12 h. The solvent was then removed in vacuo and the crude solid was purified via LCMS to yield 6 mg of a white solid (58% yield; mixture of isomers). Expected mass=555. Observed mass=556.
