Using 1,4-dichlorobut-2-yne, (R)-(2-((1H-indol-3-yl)methyl)piperazin-1-yl)(3,5-bis(trifluoromethyl)phenyl)methanone to produce (R)-(2-((1H-indol-3-yl)methyl)-4-(4-chlorobut-2-yn-1-yl)piperazin-1-yl)(3,5-bis(trifluoromethyl)phenyl)methanone, 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"
    ]
}
