Methanol → Methyl 2-amino-3-(3,5-difluorophenyl)propanoate hydrochloride

Participants

Reaction Steps

1.05 g (5.0 mmol) of 2-amino-3-(3,5-difluoro-phenyl)-propionic acid (1.05 g, 5 mmol) was dissolved in 30.0 mL of MeOH, then 1.0 mL of thionyl chloride was added dropwise. The mixture was refluxed overnight. Evaporation of the solvent yielded the solid 2-Amino-3-(3,5-difluoro-phenyl)-propionic acid methyl ester HCl salt (1.26 g, 100%), and it was used directly in the next step.
