Using 3,3-difluoropyrrolidine, tert-butyl (S)-(3-chloro-7-(2-fluoropyridin-3-yl)-5'H-spiro[chromeno[2,3-c]pyridine-5,4'-thiazol]-2'-yl)carbamate to produce tert-butyl (S)-(3-(3,3-difluoropyrrolidin-1-yl)-7-(2-fluoropyridin-3-yl)-5'H-spiro[chromeno[2,3-c]pyridine-5,4'-thiazol]-2'-yl)carbamate, 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"
    ]
}
```
