Reaction Steps

Example 11(b) was prepared by the reaction of 7-chloro-2-[(R)-3-methoxypyrrolidine-1-carbonyl]thieno[3,2-b]pyridine 4b (417 mg, 1.40 mmole) with methyl 6-hydroxy-2-methylbenzo[b]thiophene-3-carboxylate 11a (417 mg, 2.11 mmole) and Cs2CO3 (2.29 g, 7.02 mmole) in a manner as previously described for example 1 to give 290 mg (43%) of a yellow solid. 1H NMR (DMSO-d6): δ8.58 (1H, d, J=5.4 Hz), 8.39 (1H, d, J=9.0 Hz), 8.07 (1H, s), 8.02 (1H, d, J=2.3 Hz), 7.42 (1H, dd, J=2.3, 9.0 Hz), 6.79 (1H, d, J=5.4 Hz), 4.08–3.99 (3H, m), 3.87–3.86 (2H, m), 3.91 (3H, s), 3.64–3.59 (2H, m), 3.27, 3.24 (3H, s), 2.82 (3H, s).
