Hydrogen chloride (4 M in 1,4-dioxane) (5 mL, 20 mmol) was added to an ambient temperature solution of 2-(acetylamino)-3-(4-bromophenyl)propanoic acid (10 g, 34.9 mmol) in methanol (50 mL). After stirring at ambient temperature overnight, the reaction mixture was concentrated in vacuo to afford methyl 2-(acetylamino)-3-(4-bromophenyl)propanoate which was used in the subsequent step without further purification.
