Using 4-bromo-4-oxobutane-1,2,3-triyl triacetate, 3-(3-(acetoxymethyl)-5-amino-2,4,6-triiodobenzamido)propane-1,2-diyl diacetate to produce 4-((3-(acetoxymethyl)-5-((2,3-diacetoxypropyl)carbamoyl)-2,4,6-triiodophenyl)amino)-4-oxobutane-1,2,3-triyl triacetate, 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"
    ]
}
