Using nnm, (2S,5R)-1-((tert-butoxycarbonyl)-L-leucyl)-5-ethynylpyrrolidine-2-carboxylic acid to produce tert-butyl ((S)-1-((2S,5R)-2-carbamoyl-5-ethynylpyrrolidin-1-yl)-4-methyl-1-oxopentan-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"
    ]
}
