Reaction Steps
The hydrolysis of the (RS)-5-(5-bromo-2-fluoro-phenyl)-5-methyl-imidazolidine-2,4-dione with 6 N sodium hydroxide solution and esterification of the resulting (RS)-2-amino-2-(5-bromo-2-fluoro-phenyl)-propionic acid with methanol and thionylchloride yielded the (RS)-2-amino-2-(5-bromo-2-fluoro-phenyl)-propionic acid methylester as a light yellow oil. The purity of the product allowed using it in the next step without further purification. Mass (calculated) C10H11BrFNO2 [276.107]; (found) [M+H]+=276, [M+2-H]+=278.
