Reaction Steps
2.5 M nBuLi in hexane (0.619 ml, 1.55 mmole) was added to a solution of 7-chlorothieno[3,2-b]pyridine (0.250 g, 1.47 mmole) in THF (5 ml) at −78° C. The reaction mixture was stirred at −78° C. for 30 min, and then propanoyl chloride (0.162 ml, 1.76 mmole) was added. The reaction mixture stirred at −78° C. and slowly warmed to 0° C. and quenched with H2O (10 ml), extracted with EtOAc (2×10 ml). The organic layer was dried over MgSO4 and concentrated. The residue was purified by flash column chromatography eluting with 10-70% EtOAc in hexane to a off-white solid (0.084 g, 25%). 1H NMR (300 MHz, CDCl3) δ8.66 (1H, d, J=4.9 Hz), 8.12 (1H, s), 7.38 (1H, d, J=4.9 Hz), 3.09 (2H, q, J=7.3 Hz), 1.29 (3H, t, J=7.3 Hz,); ESIMS (MH+): 225.95.
