Procedure

To a solution of N-(4-chlorobenzyl)-4-hydroxy-2-iodothieno[2,3-b]pyridine-5-carboxamide (Example No. 2) (0.500 g) in pyridine (5 mL) is added CuCN (0.201 g). The reaction is heated to reflux and stirred for 18 h. The reaction mixture is purified via column chromatography (CH2Cl2:CH3OH; 98:2). Fractions homogeneous by TLC are combined and concentrated in vacuo to yield a pale yellow solid which is recrystallized from methanol to yield 0.100 g (26%) of the title compound as an off-white solid.
