Using methyl 2-amino-5-(1-((3-(2-(tert-butoxy)-2-oxoethoxy)benzyl)oxy)-2-methylindolizine-3-carbonyl)benzoate to produce 2-(3-(((3-(4-amino-3-(methoxycarbonyl)benzoyl)-2-methylindolizin-1-yl)oxy)methyl)phenoxy)acetic acid, 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"
    ]
}
