Using (tert-butoxycarbonyl)-L-serine, (4-((2-chlorobenzyl)carbamoyl)piperidin-4-yl)methyl (4-(trifluoromethyl)phenyl)carbamate to produce tert-butyl (S)-(1-(4-((2-chlorobenzyl)carbamoyl)-4-((((4-(trifluoromethyl)phenyl)carbamoyl)oxy)methyl)piperidin-1-yl)-3-hydroxy-1-oxopropan-2-yl)carbamate, 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"
    ]
}
