Procedure

A solution of 2-methyl-6-[thieno[3,2-b]pyridin-7-yloxy]benzofuran-3-carboxylic acid 100 (70 mg, 0.215 mmole), 6-Morpholin-4-yl-pyridin-3-ylamine (77 mg, 0.43 mmole), HATU (163 mg, 0.43 mmole), and diisopropylethylamine (75 μl, 0.43 mmole) were stirred in DMF (2 ml) at ambient temperature for 17 hr. The mixture was then added dropwise to a solution of cold aqueous NaHCO3 resulting in a precipitate which was collected by filtration. This material was purified on silica gel using a gradient of 0 to 5% methanol in a 1:1 mixture of ethyl acetate and dichloromethane as eluent to give 77 mg (74%) of a lavander solid. 1H NMR (CD3CN) δ 8.50 (1H, d, J=5.3 Hz), 8.37 (1H, d, J=2.5 Hz), 8.29 (1H, s), 7.92–7.88 (3H, m), 7.54 (1H, d, J=5.3 Hz), 7.45 (1H, d, J=2.0 Hz), 7.23 (1H, dd, J=8.6, 2.0 Hz), 6.78 (1H, d, J=9.1 Hz), 6.64 (1H, d, J=5.3 Hz), 3.76 (4H, t, J=4.9 Hz), 3.44 (4H, t, J=4.9 Hz), 2.72 (3H, s).
