실험 절차

A solution of the product of Example 79B (5.47 g, 52 mmol) and aqueous hydroxylamine (Aldrich, 50%, 2.3 mL, 78 mmol) in methanol (50 mL) was stirred at 65° C. for 1 hour and then concentrated under reduced pressure to remove the volatiles. The residue was triturated with EtOAc (30 mL). The precipitates were collected by filtration and dried to give the titled compound. 1H NMR (300 MHz, DMSO-d6) δ 6.14 (s, 2 H), 9.03 (s, 2 H), 9.18 (s, 1 H), 10.06 (s, 1 H) ppm; MS (DCI/NH3) m/z 139 (M+H)+, 156 (M+NH4)+.
