Reaction Steps
Racemic 3-(carbomethoxy)tyrosine methyl ester hydrochloride (example 119) was coupled to the carboxylic acid of example 2 in the usual manner. The phenolic hydroxyl group was alkylated with methyl bromoacetate in the usual manner (K2CO3/acetone at reflux) and saponified to give the title compound of example 126.
