Participants

Reaction Steps

Add 1M LAH in THF (20 mL, 20 mmol) to 3-bromo-6-chloro-2-fluoro-benzaldehyde (Preparation 7) (4.9 g, 20 mmol) in THF (20 mL) at −78° C. Stir for 15 minutes and warm up to room temperature. Add reaction mixture into ice and water. Add 1M HCl (5 mL, 5 mmol) to dissolve the solid. Extract the mixture with ethyl acetate (50 mL), dry with magnesium sulfate, filter and evaporate solvent under reduced pressure to obtain 4.6 g (94%) of the title compound as a white solid.
