Reaction Steps

Tyrosine (20 g) is dissolved in HBr (100 ml, 48% diluted with 200 ml water). To the cooled solution NaNO2 in 30 ml water is added dropwise. The product is extracted with ethyl acetate and after common treatment 2-bromo-3-(4-hydroxyphenyl)-propionic acid is obtained, which is used without purification for the next step.
