Using methyl 4-(3,4-dibromophenyl)-2-methyl-5-oxo-4,5,6,8-tetrahydro-1H-pyrano[3,4-b]pyridine-3-carboxylate to produce 9-(3,4-dibromophenyl)-5,9-dihydro-3H-furo[3,4-b]pyrano[4,3-e]pyridine-1,8(4H,7H)-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"
    ]
}
