Using sulfite, tert-butyl (S)-5-((S)-2-((R)-4-benzyl-2-oxooxazolidin-3-yl)-1-(4-chloro-3-fluorophenyl)-2-oxoethyl)-2,2-dimethylpyrrolidine-1-carboxylate to produce (S)-2-((S)-1-(tert-butoxycarbonyl)-5,5-dimethylpyrrolidin-2-yl)-2-(4-chloro-3-fluorophenyl)acetate, 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"
    ]
}
```
