methyl 2-(2-methylquinolin-7-yl)acetate (5.78 g, 26.9 mmol) in THF (50 mL) was added 1M LAH (40.3 mL, 40.3 mmol) in THF at 0° C., followed by stirring at 0° C. for 3 hours. Sodium sulfate decahydrate (10.0 g) was added and stirred at ambient temperature for 30 minutes. The solid was removed by filtration and washed with ethyl acetate (100 mL). The filtrate was concentrated and the residue obtained was purified by flash chromatography (ethyl acetate) on silica gel to give 2-(2-methylquinolin-7-yl)ethanol (2.35 g, 12.6 mmol, 47% yield) as a solid.
