Using (3S,4R)-1-(tert-butyl)-4-(2,4-difluorophenyl)pyrrolidine-3-carboxylic acid, (S)-N-(1-(5-chloro-2-(piperidin-4-yl)phenyl)ethyl)acetamide to produce N-((S)-1-(2-(1-((3S,4R)-1-(tert-butyl)-4-(2,4-difluorophenyl)pyrrolidine-3-carbonyl)piperidin-4-yl)-5-chlorophenyl)ethyl)acetamide, 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"
    ]
}
