77% | at 0℃; for 24 h; Reflux | Diethyl 2,2'-bipyridine-5,5'-dicarboxylate Procedure: Bipy55'DC (200 mg, 0.82 mmoles) and EtOH (13 mL) were added to a dried flask and stirred on ice. Thionyl chloride (1.3 mL) was added dropwise on ice, after which the flask was fitted with a reflux condenser and heated at reflux. After 24 hr, the reaction was cooled on ice and quenched by the dropwise addition of saturated Na2CO3 (20 mL). The aqueous layer was extracted with CH2Cl2 (4*20 mL) and the combined organics were dried over Na2SO4(s), and concentrated under reduced pressure. The crude product was then purified by chromatography on silica (3percent acetone in 1:1 DCM/hexanes) to afford the title compound (190 mg, 77percent) as a white solid. 1H NMR (500 MHz, CDCl3) δ 9.32 (dd, J=0.5, 2.0 Hz, 1H), 8.59 (dd, J=0.5, 8.5 Hz, 1H), 8.46 (dd, J=2.0, 8.5 Hz, 1H), 4.47 (q, J=7.5 Hz, 2H), 1.46 (t, J=7.5 Hz, 3H); 13C NMR (125 MHz, CDCl3) δ 165.2, 158.3, 150.6, 138.1, 126.6, 121.3, 61.6, 14.3; HRMS (ESI) m/z 301.1193 [calc'd for C16H17N2O4 (M+H)+ 301.1183]. |
