Using 3-(dimethylamino)-1-(thiophen-2-yl)propan-1-one, dimethyl 2-(((S)-1-((S)-2-(tert-butoxycarbonyl)pyrrolidin-1-yl)-1-oxopropan-2-yl)amino)malonate to produce dimethyl 2-(((S)-1-((S)-2-(tert-butoxycarbonyl)pyrrolidin-1-yl)-1-oxopropan-2-yl)amino)-2-(3-oxo-3-(thiophen-2-yl)propyl)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"
    ]
}
