Participants

Reaction Steps

To a solution of 6-(7-chlorothieno[3,2-b]pyridin-2-yl)pyridine-2-carbaldehyde 52a (0.127 g, 0.46 mmole) in THF (20 ml) was added 2.0 M dimethylamine in THF (1.5 ml, 2.3 mmole), NaCNBH3 (0.063 g, 0.92 mmole) and NaOAc (0.076 g, 0.92 mmole). The reaction mixture was stirred at room temperature overnight and concentrated. The residue was purified by flash column chromatography eluting with 2–10% CH3OH in CHCl3 to give a yellow solid (0.086 g, 61%). 1H NMR (300 MHz, CD3OD) δ 8.50 (1H, d, J=5.3 Hz), 8.11 (1H, s), 8.03 (1H, d, J=7.9 Hz), 7.90 (1H, t, J=7.9 Hz), 7.41 (2H, m), 4.16 (2H, s), 2.71 (6H, s).
