Procedure
3,5-Dibromo-benzamide and pyrazin-2-ylamine were coupled to give 3-bromo-5-(pyrazin-2-ylamino)-benzamide as described for Example 44. 3-Bromo-5-(pyrazin-2-ylamino)-benzamide was converted to 3-(1H-indol-4-yl)-5-(pyrazin-2-ylamino)-benzamide as described in Example 75. 1H NMR (400 MHz, CDCl3): δ 10.61 (s, 1H), 8.24 (t, J=1.8 Hz, 1H), 8.17-8.12 (m, 3H), 8.06 (s, 1H), 7.88 (s, 1H), 7.78 (t, J=1.5 Hz, 1H), 7.40 (dd, J=6.6, 2.1 Hz, 1H), 7.30 (d, J=3.1 Hz, 1H), 7.21-7.16 (m, 2H), 6.74 (d, J=2.7 Hz, 1H).
