62% | Stage #1: With n-butyllithium In tetrahydrofuran; hexane at -78℃; for 0.333333 h; Stage #2: With methanol; water In tetrahydrofuran; hexane at 20℃; for 1 h; |
Dissolve 7-bromo-thieno[3,2-]pyridine (3.69 g, 17 mmol) in dry THF (20 mL) and cool to -78 0C. Add n-BuLi (1.6 M in hexane, 21.2 mL, 34 mmol) slowly to the mixture at -78 0C and stir at -78 0C for 20 min. Add MeOH/H2O=l/l (20 mL) and stir at room temperature for 1 h. Extract the reaction mixture with CH2Cl2. Wash the organic portion with saturated NaCl solution, dry over Na2SO4, and evaporate. Purify the resulting residue using silica gel chromatography, eluting with 100percent hexane to hexane:ethyl acetate = 10:1 to give the title compound (1.44 g, 62percent). ES/MS m/z 136 (M+ 1)+. |

3.69 g of 7-Bromo-thieno[3,2-b]pyridine (17 mmol) is dissolved in 20 ml of dry THF and cooled to -780C. 21.2 ml of n-BuLi 1.6M in hexane (34 mmol) is added slowly to the mixture at -780C and stirred at -780C for 20 min, and 20 ml of MeOH/H2O=l/l is added and stirred at room temperature for Ih. The reaction mixture is extracted with CHC12. The separated CH2Cl2 layer is washed with sat. NaCl, dried over Na2SO4 and evaporated. The crude product is applied onto a silica-gel chromatography column (Hexane -> Hexane:AcOEt=-10:l) to give 1.44 g of the title compound.
