This material was prepared from the reaction of methyl 6-hydroxy-2-methylbenzo[b]thiophene-3-carboxylate 11a (283 mg, 1.00 mmole) with 7-chloro-2-[(R)-3-hydroxypyrrolidine-1-carbonyl]thieno[3,2-b]pyridine 4a and Cs2CO3 (977 mg, 3.00 mmole) in a manner as previously described for example 1. The crude product was then reacted with LiOH.H2O (227 mg, 5.4 mmole) in a manner similar to that described for example 11c to give a yellow solid (202 mg, 45%). 1H NMR (DMSO-d6, 300 MHz) δ 8.58 (1H, d, J=5.31 Hz), 8.44 (1H, d, J=8.84Hz), 8.14, 8.07 (1H, s), 8.00 (1H, s), 7.39 (1H, dd, J=2.40, 8.97 Hz), 6.78 (1H, d, J=5.56 Hz), 4.38, 4.33 (1H, br s), 4.01–3.91 (1 H, m), 3.68–3.56 (2H, m), 3.49–3.22 (2H, m), 2.81 (3H, s), 2.07–1.79 (2H, m).
