9% | With tert.-butylnitrite; copper(ll) bromide; In acetonitrile; for 3h; | INTERMEDIATE 12; 7-Bromo-4H-benzori,41oxazm-3-one; Intermediate 11 (0.5 g, 3.0 mmol), copper(II) bromide (0.67 g, 3.3 mmol) and tert- butyl nitrite (0.52 mL, 4.3 mmol) were combined in acetonitrile (30 mL) and stirred for 3 h. The mixture was partitioned between EtOAc (100 mL) and water (100 mL). The organics were dried (MgSO4), filtered and concentrated in vacuo to give a crude product which was purified by prep ηPLC to yield the title compound as a beige solid (65 mg, 9%). δη (DMSO-d6) 4.60 (2H, br s), 6.83 (IH, d, J 8.3 Hz), 7.10-7.20 (2H, m), 10.83 (IH, br s). |
