[Lithium 7-chlorothieno[3,2-b]pyridine-2-carboxylate (100 mg, 455 μmol) was dissolved in CH2Cl2 (5 mL) with one drop of DMF and oxalyl chloride (2 mL) was added. The mixture was stirred at RT for one hour then concentrated and dried under high vacuum. Morpholine (60 μl, 683 μmol) was then added to the mixture with N-ethyl-N-isopropylpropan-2-amine (238 μl, 1366 μmol) and the mixture was stirred for 20 hours. The mix was then concentrated and purified using 0 to 100% 90/10/1 CH2Cl2/MeOH/ammonium hydroxide in CH2Cl2 to afford (7-chlorothieno[3,2-b]pyridin-2-yl)(morpholino)methanone.
