Using (R)-N-(2-(5-bromo-2-fluorophenyl)-1-((cyanomethyl)thio)propan-2-yl)-N-(2,4-dimethoxybenzyl)-2,2,2-trifluoroacetamide to produce (R)-N-(2-(5-bromo-2-fluorophenyl)-1-((cyanomethyl)thio)propan-2-yl)-2,2,2-trifluoroacetamide, 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"
    ]
}
