Using 3-isopropoxy-4-(tributylstannyl)cyclobut-3-ene-1,2-dione, 2-((3S,4R)-3-hydroxy-6-iodo-2,2-dimethylchroman-4-yl)isoindolin-1-one to produce 3-((3S,4R)-3-hydroxy-2,2-dimethyl-4-(1-oxoisoindolin-2-yl)chroman-6-yl)-4-isopropoxycyclobut-3-ene-1,2-dione, 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"
    ]
}
