Procedure

This material was prepared by the reaction of 7-chloro-2-(1-methyl-1H-imidazol-2-yl)thieno[3,2-b]pyridine 1e (114 mg, 0.46 mmole) with 6-hydroxy-2-ethylbenzofuran-3-carboxylic acid methylamide 14c (120 mg, 0.55 mmole) and Cs2CO3 (594 mg, 1.82 mmole) in a manner as previously described for example 1 to give 60 mg (30%) of a tan solid. 1H NMR (DMSO-d6) δ 8.49 (1H,d, J=5.6 Hz), 8.00 (1H, d, J=4.6 Hz), 7.89 (1H, s), 7.82 (1H, d, J=8.6 Hz), 7.67 (1H, s), 7.41 (1H, s), 7.26 (1H, d, J=8.6 Hz), 7.03 (1H, s), 6.68 (1H, d, J=5.6 Hz), 3.99 (3H, s), 3.04 (2H, q, J=7.6 Hz), 2.81 (3H, d, J=4.6 Hz), 1.28 (3H, t, J=7.3 Hz).
