Using trifluoroaceticacid, (R)-N-(1-(4-bromophenyl)-2-(pyrrolidin-1-yl)ethyl)-2-((cyanomethyl)(3,4-dichlorophenyl)amino)-N-methylacetamide to produce (R)-2-((2-amino-2-oxoethyl)(3,4-dichlorophenyl)amino)-N-(1-(4-bromophenyl)-2-(pyrrolidin-1-yl)ethyl)-N-methylacetamide, 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"
    ]
}
