실험 절차

The product from Example 6A (223 mg, 0.396 mmol) in pyridine (3 mL) was treated with hydroxylamine hydrochloride (30 mg, 0.435 mmol) and heated at reflux. After 30 minutes, the mixture was allowed to cool to ambient temperature and partitioned between ethyl acetate and H2O. The separated organic phase was washed with 1 N HCl, brine, dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure. The residue was purified by flash chromatography (75% ethyl acetate/hexanes) to provide the title compound as a light yellow solid (91 mg, 40% yield). 1H NMR (300 MHz, DMSO-d6) δ 13.32 (bs, 1H), 10.2-10.4 (bs, 2H), 9.89 (s, 1H), 9.43 (d, 1H), 8.75 (m, 1H), 8.03-8.17 (m, 3H), 7.8-7.95 (m, 2H), 7.45 (m, 1H), 7.25 (m, 1H), 7.1 (m, 1H), 6.98 (m, 1H), 6.75 (m, 1H), 6.58 (m, 1H), 6.52 (m, 1H), 6.4 (m, 1H), 1.98 (s, 3H); MS (ESI) 577 (M−H)−.
