Using n,n-dimethylformamide, tert-butyl 2-(2-oxo-2,3,4,5,5a,6-hexahydroazocino[4,3,2-cd]indol-7(1H)-yl)acetate to produce 3,3-dimethyl-2-(1-methyl-2-oxo-2,3,4,5,5a,6-hexahydroazocino[4,3,2-cd]indol-7(1H)-yl)butanoic acid, please predict the condition, including solvent and agent in SMILES notation in json format like:

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