Reaction Steps

This material was prepared from lithium 7-chlorothieno[3,2-b]pyridine-2-carboxylate (0.214 g, 1.0 mmole) by treatment with thionyl chloride followed by reaction of the resultant acyl chloride with (3R)-N,N-dimethylpyrrolidin-3-amine (0.114 g, 1.0 mmole) and Et3N (0.139 ml, 1.0 mmole), in a manner as previously described for example 9d to give a brown solid (0.134 g, 43%). 1H NMR (300 MHz, CD3OD) δ7.24 (1H, d, J=5.1 Hz), 6.57 (1H, d, J=8.48 Hz), 6.15 (1H, d, J=5.1 Hz), 2.70 (1H, m), 2.51 (2H, m), 2.24 (1H, m), 2.04 (1H, m), 1.49 (1H, m), 0.93 (3H, s), 0.90 (3H, s), 0.52 (1H, m); ESIMS (MH+): 310.10.
