Using 4-bromobutanenitrile, 8-(2-aminobenzyl)-4-(cyclohexylamino)-1-(3-fluorophenyl)-1,3,8-triazaspiro[4.5]dec-3-en-2-one to produce 4-((2-((4-(cyclohexylamino)-1-(3-fluorophenyl)-2-oxo-1,3,8-triazaspiro[4.5]dec-3-en-8-yl)methyl)phenyl)amino)butanenitrile, 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"
    ]
}
