Using 2-chloro-1-(4-fluorophenyl)ethan-1-one, (S)-1-(3-ethyl-5-(1-methyl-1H-tetrazol-5-yl)phenyl)-3-(piperidin-3-ylmethyl)urea to produce (S)-1-(3-ethyl-5-(1-methyl-1H-tetrazol-5-yl)phenyl)-3-((1-(2-(4-fluorophenyl)-2-oxoethyl)piperidin-3-yl)methyl)urea, 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"
    ]
}
