Synthesis

File:Tiropramide synthesis.svg

The acylation of racemic tyrosine (1) with benzoyl chloride gives N,O-dibenzoyl-tyrosine (2). Amide formation with dipropylamine (3) using the mixed anhydride method gives the intermediate (4). Hydrolysis of the phenolic ester with sodium hydroxide forms (5), which is alkylated with Template:Chem2 to produce the ether tiropramide.[2][3]
