Using tert-butyl 2-((tert-butoxycarbonyl)(5-ethoxy-5-oxopent-3-en-1-yl)carbamoyl)-5-fluoro-3-iodo-1H-indole-1-carboxylate to produce di-tert-butyl 5-(2-ethoxy-2-oxoethylidene)-7-fluoro-1-oxo-1,3,4,5-tetrahydroazepino[3,4-b]indole-2,10-dicarboxylate, please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
    ],
    "agent": [

        "Cl"
    ]
}
