Participants

Reaction Steps

This material was prepared by the reaction of 7-chloro-2-[(S)-2-(methoxymethyl)pyrrolidine-1-carbonyl]thieno[3,2-b]pyridine 2a (153 mg, 0.5 mmole) with 6-hydroxy-2-methylbenzo[b]thiophene-3-carboxylic acid methylamide 1d (164 mg, 0.7 mmole) and Cs2CO3 (868 mg, 2.7 mmole) in a manner as previously described for example 1 to give 178 mg (73%) of a yellow solid. 1H NMR (DMSO-d6): δ8.57 (1H, d, J=5.4 Hz, 8.29 (1H, q, J=4.5 Hz), 8.02 (1H, s), 7.95 (1H, d, J=2.2 Hz), 7.85 (1H, d, J=8.8 Hz), 7.32 (1H, dd, J=2.2, 8.8 Hz), 6.75 (1H, d, J=5.4 Hz), 4.37-4.23 (1H, m), 3.95-3.74 (2H, m), 3.60-3.48 (2H, m), 3.27 (3H, s), 2.83 (3H, d, J=4.5 Hz), 2.60 (3H, s), 2.08-1.81 (4H, m). Anal. Calcd. for C25H25N3O4S2: C, 60.58; H, 5.08; N, 8.48; S, 12.94. Found: C, 60.55; H, 5.33; N, 8.27; S, 12.68.
