Reaction Steps

2-Mercaptoethanol (0.11 mL, 1.51 mmol, 2.0 eq) is added at room temperature to a stirred solution of 3-bromo-6-methoxy-quinoline (200 mg, 0.76 mmol, 1.0 eq) in N,N-dimethylformamide (10 mL), followed by sodium hydride (50%, 174 mg, 3.78 mol, 5.0 eq). After 4 hours stirring at 80° C., solvent is evaporated and the residue is extracted with ethyl acetate (3×50 mL) and water (10 mL). The combined organic layers are dried over sodium sulfate, filtered and concentrated to give a crude product that is purified by column chromatography (silica gel, eluent: ethyl acetate:hexane, 1:4 to 1:2, v/v) to afford 2-(6-methoxy-quinolin-3-ylsulfanyl)-ethanol as a yellow viscous oil (140 mg, 79% yield).
