Using 1-bromobutane, 5-chloro-N-(6,7-dihydro-5H-pyrano[3,2-d]thiazol-2-yl)-2-methoxybenzamide to produce (Z)-N-(1-butyltetrahydro-5H-pyrano[3,2-d]thiazol-2(1H)-ylidene)-5-chloro-2-methoxybenzamide, 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"
    ]
}
