Reaction Steps

To a solution of 3-pyridinecarboxaldehyde (5.0 mL, 53 mmol) in THF at -78° C. was added 2-thienyllithium (1.0M in THF, 64 mL, 64 mmol) and the reaction mixture was stirred for 2 hours at -78° C. The reaction mixture was quenched with saturated aqueous NH4Cl and extracted with ether. The organic phase was dried over MgSO4, filtered, and concentrated in vacuo. Chromatography on silica gel (5%, then 10% methanol/CHCl3) gave 2-(3-pyridylhydroxymethyl)thiophene (6.30 g, 62% yield).
