Reaction Conditions

Reaction Steps

To a stirred solution of methyl 2-(2-fluoro-4-nitrophenyl)acetate (3.0 g, 14.0 mmol, 1.0 eq) in methanol (30 mL) was added NaBH4 (2.08 g, 36.3 mmol, 4.0 eg) at 0° C. and stirred at 70° C. for 16 h, then the methanol was evaporated and the residue was diluted with water (30 mL), the pH adjusted to being neutral with 2N HCl and the mixture extracted with EtOAc (50 mL×3). The organic layer was separated, washed with brine, dried over Na2SO4 and the solvent evaporated to yield 2-(2-fluoro-4-nitrophenyl)ethanol (2.0 g, 77%) as a viscous oil (TLC system: EtOAc/PE (3:7), Rf: 0.3).
