Using (methoxycarbonyl)-L-valine, (S)-4-(4-bromophenyl)-2-(4-cyclopropyl-2,5-dihydro-1H-pyrrol-2-yl)-1H-imidazole to produce methyl ((S)-1-((S)-2-(4-(4-bromophenyl)-1H-imidazol-2-yl)-4-cyclopropyl-2,5-dihydro-1H-pyrrol-1-yl)-3-methyl-1-oxobutan-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"
    ]
}
