Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Cyclohexaneacetic acid | HCID 21363 | — |
| Reactant | 2-Methylpropyl (2S)-2-aminopropanoate hydrochloride | HCID 86584981 | — |
| Product | N-(cyclohexyIacetyl)-L-alanine iso-butyl ester | HCID 54223838 | — |
Reaction Steps
Following General Procedure BB above, and using cyclohexylacetic acid (Aldrich) and L-alanine iso-Butyl Ester hydrochloride (from Example BB above), the title compound was prepared as a solid having a melting point of 92° C.-93° C. The reaction was monitored by tlc on silica gel (Rf=0.39 in 1:3 EtOAc:hexane) and purification was by extraction with Et2O followed by washes with aqueous K2CO3 and aqueous HCl.
