Using (9H-fluoren-9-yl)methyl (S)-2-benzyl-3-((1-(2-ethoxy-2-oxoethyl)-3-(pyridin-4-yl)-1H-pyrazol-5-yl)amino)-3-oxopropanoate, tetrabutylammonium to produce ethyl (S)-2-(5-(2-amino-3-phenylpropanamido)-3-(pyridin-4-yl)-1H-pyrazol-1-yl)acetate, 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",
