To a stirred solution of methyl 3-bromo-quinoline-6-carboxylate (1.09 g, 4 mmol) in THF (50 mL) at 0° C. was added LiAlH4 (0.155 g, 4 mmol) in small portions. The resulting mixture was stirred at 0° C. for 0.5 h. Water (0.2 mL) was added dropwise, followed by 0.2 mL of 10% aq. NaOH and 0.2 mL of water. The solid was removed and the solvent was concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with EtOAc/hexane gradient to afford the title compound (413 mg, 42%). LCMS (method A): [MH]+=238/240, tR=4.453 min.
