Using (2R,3R)-5,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)chroman-3-yl 3,4,5-trihydroxybenzoate to produce (2R,2'R,3R,3'R)-(3,4,5-trihydroxy-6-oxo-6H-benzo[7]annulene-1,8-diyl)bis(5,7-dihydroxychromane-2,3-diyl) bis(3,4,5-trihydroxybenzoate), 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"
    ]
}
