Procedure
This material was prepared by the reaction 7-chloro-2-(1-methyl-1H-imidazol-2-yl)thieno[3,2-b]pyridine 1e (0.084 g, 0.34 mmole) with 2-ethyl-6-hydroxy-N,1-dimethyl-1H-indole-3-carboxamide 73 g (0.078 g, 0.33 mmole) and Cs2CO3 (0.111 g, 0.34 mmole) in a manner as previously described for example 1 to give an off-white solid (0.058 g, 40%). 1H NMR (300 MHz, CD3OD 67 8.27 (1H, d, J=5.4 Hz), 7.68 (1H, d, J=8.6 Hz), 7.59 (1H, s), 7.24 (1H, d, J=1.9 Hz), 7.17 (1H, s), 6.96 (1H, s), 6.90 (1H, dd, J=1.9, 8.6 Hz), 6.50 (1H, d, J=5.4 Hz), 3.87 (3H, s), 3.58 (3H, s), 3.01 (2H, m), 2.85 (3H, s), 1.14 (3H, m). HRMS (MH+): Calcd: 446.1655; Found: 446.1651.
