Using diethyl 1-((1-(tert-butoxycarbonyl)-4-(((tert-butoxycarbonyl)amino)methyl)piperidin-4-yl)methyl)-1H-indole-2,6-dicarboxylate to produce ethyl 1'-oxo-2',3'-dihydro-1'H,5'H-spiro[piperidine-4,4'-[1,4]diazepino[1,2-a]indole]-8'-carboxylate, 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"
    ]
}
