Participants

Reaction Steps

was prepared by the reaction of 7-chloro-thieno[3,2-b]pyridine-2-carboxylic acid (0.57 g, 2.67 mmol) with 2.0 M N,N-dimethylamine in THF (1.60 mL, 3.20 mmol) and Et3N (0.447 mL, 3.20 mmol) in a manner as described in Method A to give the desired amide as brown solid (0.54 g, 84%). 1H NMR (300 MHz, CDCl3) δ 8.63 (d, 1H, J=4.85 Hz), 7.74 (s, 1H), 7.35 (d, 1H, J=5.02 Hz), 3.28 (s, 3H), 3.22 (s, 3H); ESIMS (MH+): 240.95.
