Using 4-(chloromethyl)-N,N-dimethylaniline, 5,5-dimethylimidazolidine-2,4-dithione to produce 4,4'-(((4,4-dimethyl-4H-imidazole-2,5-diyl)bis(sulfanediyl))bis(methylene))bis(N,N-dimethylaniline), please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
    ],
    "agent": [

        "C(=NC1CCCCC1)=NC1CCCCC1",
        "Cl"
    ]
}
