Using ethyl (S)-2-(((3S,6R)-1-(2-(tert-butoxy)-2-oxoethyl)-2-oxo-6-phenylazepan-3-yl)amino)-4-phenylbutanoate to produce 2-((3S,6R)-3-(((S)-1-ethoxy-1-oxo-4-phenylbutan-2-yl)amino)-2-oxo-6-phenylazepan-1-yl)acetic acid, please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
    ],
    "agent": [
        "On1nnc2ccccc21",
