Using (S)-3-amino-1-(1-(5-ethylpyrimidin-2-yl)piperidin-4-yl)pyrrolidin-2-one, 4-(ethylsulfonyl)-1,2-difluorobenzene to produce (S)-1-(1-(5-ethylpyrimidin-2-yl)piperidin-4-yl)-3-((4-(ethylsulfonyl)-2-fluorophenyl)amino)pyrrolidin-2-one, 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"
    ]
}
