Reaction Conditions

Reaction Steps

To a solution of 1.0 N LAH (15.3 mL, 15.3 mmol) in THF was added diethyl 2-(2-methylquinolin-7-yl)malonate (1.15 g, 3.82 mmol) in Ether (30 mL) slowly at 0° C. The reaction mixture was stirred at 0° C. for 2 hours. Sodium sulfate decahydrate (2.0 g) was added and stirred at ambient temperature for 30 minutes. The solid was removed by filtration and washed with ethyl acetate (50 mL). The filtrate was concentrated and the residue obtained was purified by C-18 reverse phase flash chromatography (Biotage SP4 unit, C-18 40M column, 0-70% CH3CN/water gradient; 30 CV) to give 2-(2-methylquinolin-7-yl)propane-1,3-diol (0.34 g, 1.56 mmol, 41.0% yield) as a solid.
