Using tert-butyl ((S)-1-((2S,4S)-2-cyano-4-fluoropyrrolidin-1-yl)-3,3-bis(4-fluorophenyl)-1-oxopropan-2-yl)carbamate to produce (2S,4S)-1-((S)-2-amino-3,3-bis(4-fluorophenyl)propanoyl)-4-fluoropyrrolidine-2-carbonitrile, 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"
    ]
}
