Using diethyl propanedioate, tert-butyl (R)-(4-(5-(3-fluoro-4-nitrophenyl)-1,3,4-thiadiazol-2-yl)-1-(6-(trifluoromethyl)pyridin-3-yl)butan-2-yl)carbamate to produce diethyl (R)-2-(5-(5-(3-((tert-butoxycarbonyl)amino)-4-(6-(trifluoromethyl)pyridin-3-yl)butyl)-1,3,4-thiadiazol-2-yl)-2-nitrophenyl)malonate, 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"
    ]
}
