Tetrahydrofuran → 1-Cyclopropyl-1-(4-fluorophenyl)ethanol

참여 물질

반응 단계

To a solution of cyclopropyl-4-fluorophenyl ketone (523 mg, 3.19 mmol) in THF (10 mL) at 0° C. under N2 was added 3 M methyl magnesium bromide (1.7 mL, 5.1 mmol) in Et2O. After 90 minutes at 0° C., the reaction was quenched by addition of brine (10 mL) and diluted with Et2O (100 mL). The organic solution was washed with saturated NaHCO3 (100 mL) and brine (100 mL). Column purification (hexanes:EtOAc 9:1) yielded 1-cyclopropyl-1-(4-fluorophenyl)ethanol (512 mg, 89%) as a colorless oil.
