Participants

Reaction Steps

This material was prepared by the reaction of 7-chloro-2-(1-methyl-1H-imidazol-2-yl)thieno[3,2-b]pyridine 1e with 6-hydroxy-2-methyl-benzofuran-3-carboxylic acid isobutyl amide 84b and Cs2CO3 in a manner as previously described for example 1. 1H NMR (CD3CN) δ 8.48 (1H,d, J=5.6 Hz), 7.81 (1H, d, J=8.3 Hz), 7.74 (1H, s), 7.43 (1H, d, J=2.0 Hz), 7.21 (1H, dd, J=8.6, 2.3 Hz), 7.17 (1H, s), 7.04 (1H, s), 6.70 (1H,m), 6.67 (1H, d, J=5.6 Hz), 3.97 (3H, s), 3.23 (2H, t, J=6.6 Hz), 2.66 (3H, s),1.78 (1H,m), 0.98 (6H, d, J=6.6 Hz).
