Participants

Reaction Steps

This material was prepared from lithium 7-chlorothieno[3,2-b]pyridine-2-carboxylate (1.0 g, 4.68 mmole) by treatment with thionyl chloride followed by reaction of the resultant acyl chloride with 2-(methylamino)ethanol (0.414 ml, 5.15 mmole) and Et3N (0.718 ml, 5.15 mmole), in a manner as previously described for example 9d to give a pale brown solid (0.624 g, 49% yield). 1H NMR (400 MHz, CDCl3) σ8.61 (1H, d, J=4.8 Hz), 7.80 (1H, s), 7.33 (1H, d, J=4.8 Hz), 3.92 (2H, m), 3.76 (2H, t, J=5.1 Hz), 3.37 (3H, s), 3.19 (1H, s); ESIMS (MH+): 259.10.
