Using (S)-1-(tert-butoxycarbonyl)-2-methylpyrrolidine-2-carboxylic acid, methyl (S)-2-amino-3-(4-(2-cyanophenoxy)phenyl)propanoate to produce tert-butyl (S)-2-(((S)-3-(4-(2-cyanophenoxy)phenyl)-1-methoxy-1-oxopropan-2-yl)carbamoyl)-2-methylpyrrolidine-1-carboxylate, 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",
        "C(=NC1CCCCC1)=NC1CCCCC1",
        "Cl"
    ]
}
