Versuchsvorschrift

The product from Example 7A (134 mg, 0.257 mmol) in pyridine (3 mL) was treated with hydroxylamine hydrochloride (20 mg, 0.283 mmol) and stirred at ambient temperature. After 3 hours, the mixture was partitioned between ethyl acetate and 1N HCl. The separated organic phase was washed with 1N HCl, saturated NaHCO3, brine, dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure. The residue was dissolved in a minimum amount of ethyl acetate and CH2Cl2 was added to effect precipitation. The solid was collected by filtration and dried under reduced pressure to provide the title compound as a white solid (123 mg, 89% yield). 1H NMR (300 MHz, DMSO-d6) δ 13.43 (bs, 1H), 10.17-10.35 (m, 1H), 9.96-10.13 (m, 1H), 9.46 (d, 1H), 8.76 (d, 1H), 8.02-8.18 (m, 3H), 7.8-7.93 (m, 2H), 6.98 (m, 1H), 6.81 (m, 1H), 6.5-6.6 (m, 2H), 6.32-6.44 (m, 2H), 6.16-6.28 (m, 2H), 5.1 (bs, 2H); MS (ESI) 535 (M−H)−.
