N-Boc-O-(2,6-Dichlorobenzyl)-L-tyrosine (I) is coupled to 4-amino-2,2,6,6-tetramethylpiperidine (II) using BOP in DMF to provide amide (III). The N-Boc protecting group of (III) is then removed by trifluoroacetic acid, yielding amine (IV). This is finally acylated with pentafluorocinnamic acid (V) in the presence of BOP/i-Pr2NEt to furnish the title compound (1,2).
