Using ((benzyloxy)carbonyl)-L-asparagine, benzyl ((2S,3R)-1-(4-(tert-butoxy)phenyl)-4-((R)-1-(tert-butyl)-2-carbamoylpyrrolidin-2-yl)-3-hydroxybutan-2-yl)carbamate to produce benzyl ((S)-4-amino-1-(((2S,3R)-1-(4-(tert-butoxy)phenyl)-4-((R)-1-(tert-butyl)-2-carbamoylpyrrolidin-2-yl)-3-hydroxybutan-2-yl)amino)-1,4-dioxobutan-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"
    ]
}
