Reaction Steps

Following the same procedure as in Example 44, step 2 (scheme 32) but substituting bromide 155 for bromide 328 (1.00 g, 3.85 mmol) and boronate 116 for 2-thiophene boronic acid (517 mg, 4.04 mmol) and heating at 120° C., the title compound 298 was obtained (270 mg, 32% yield). 1H NMR: (DMSO-d6) δ (ppm): 11.21 (bs, 1H), 8.07 (d, J=2.3 Hz, 1H), 7.80 (dd, J=8.6, 2.3 Hz, 1H), 7.49 (dd, J=3.5, 1.2 Hz, 1H), 7.16 (d, J=8.6 Hz, 1H), 7.11 (dd, J=5.1, 3.5 Hz, 1H), 7.07 (d, J=8.8 Hz, 1H).
