Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Tyrosine Methyl Ester | HCID 70652 | — |
| Reactant | (2S)-2-[[2-(3,5-difluorophenyl)acetyl]amino]propanoic acid | HCID 12135350 | — |
| Product | N-[N-(3,5-Difluorophenylacetyl)-L-alaninyl]-L-tyrosine Methyl Ester | HCID 10180420 | — |
Reaction Steps
Following General Procedure A and using N-(3,5-difluorophenylacetyl)-L-alanine (from Example B2 above) and L-tyrosine methyl ester (Bachem), the title compound was prepared as a solid (mp=85-88° C.). The reaction was monitored by tlc (Rf=0.27 in 50% EtOAc/hexanes) and the product was purified by silica gel column chromatography.
