Using 1,3-bis(4-bromophenethyl)-1,3-di-tert-butyl-1,3-dimethyldisiloxane, 3-bromobenzonitrile to produce 4',4'''-((1,3-di-tert-butyl-1,3-dimethyldisiloxane-1,3-diyl)bis(ethane-2,1-diyl))bis([1,1'-biphenyl]-3-carbonitrile), 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"
    ]
}
