Reaction Steps

The product from Example 1d (0.03 g, 0.167 mmol) was reacted with the product from Example 223c (0.060 g, 0.15 mmol) for 17.5 h following the procedure from Example 1g. Consumption of starting material required a second addition of the product from Example 1d (0.016 g, 0.09 mmol) and continued heating at 80° C. (18 h). The crude title compound was purified by HPLC with TFA providing the product as a trifluoroacetic acid salt (0.056 g, 55%). 1H NMR (300 MHz, DMSO-d6) δ ppm: 2.77 (s, 3 H) 5.12 (s, 2 H) 6.30 (d, J=6.99 Hz, 1 H) 6.79 (d, J=8.82 Hz, 2 H) 6.92-7.08 (m, 3 H) 7.25 (d, J=8.82 Hz, 2 H) 7.42-7.54 (m, 4 H) 7.81 (d, J=8.82 Hz, 1 H) 8.47 (d, J=6.99 Hz, 1 H) 9.01 (d, J=8.46 Hz, 1 H) 9.98 (s, 1 H); MS (ESI+) m/z 546.0 (M+H)+.
