Using 4-nitrobenzyl (2S,4R)-2-((1R,2R)-2-(ethoxycarbonyl)cyclopropyl)-4-((methylsulfonyl)oxy)pyrrolidine-1-carboxylate to produce (1R,2R)-2-((2S,4R)-4-((methylsulfonyl)oxy)-1-(((4-nitrobenzyl)oxy)carbonyl)pyrrolidin-2-yl)cyclopropane-1-carboxylic 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": [
        "On1nnc2ccccc21",
        "C(=NC1CCCCC1)=NC1CCCCC1",
        "Cl"
    ]
}
