Using azide, 6'-chloro-2-(3-chlorophenyl)-6-(m-tolyl)spiro[cyclohexane-1,3'-indoline]-2',4-dione to produce (3S,4R,5R)-6'-chloro-3-(3-chlorophenyl)-5-(m-tolyl)spiro[azepane-4,3'-indoline]-2',7-dione, 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"
    ]
}
