Using 3-bromopropanenitrile, 4,4',4'',4'''-(ethene-1,1,2,2-tetrayl)tetrabenzenethiol to produce 3,3',3'',3'''-((ethene-1,1,2,2-tetrayltetrakis(benzene-4,1-diyl))tetrakis(sulfanediyl))tetrapropanenitrile, 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"
    ]
