Reaction Steps

The product from Example 4A (300 mg, 1.08 mmol) in N,N-dimethylacetamide (10 mL) was treated with NaN3 (0.7 g, 10.8 mmol) and MgCl2 (1.03 g, 10.8 mmol). The mixture was heated at 150° C. for 16 hours, allowed to cool to room temperature, and poured into H2O (50 mL). The mixture was filtered and the filter cake air-dried to provide the title compound as a solid. 1H NMR (300 MHz, DMSO-d6) δ 10.14 (s, 1H), 8.10 (d, J=8.4 Hz, 2H), 7.97 (d, J=8.4 Hz, 2H), 7.71 (d, J=8.5 Hz, 2H), 7.36 (d, J=8.4 Hz, 2H), 1.29 (s, 9H); MS (ESI+) m/z 322 (M+H)+.
