Using 1-bromo-4-(difluoromethyl)benzene, (2R,3R,4S,5R,6R)-2-(acetoxymethyl)-6-(4-fluoro-3-formyl-1H-indol-1-yl)tetrahydro-2H-pyran-3,4,5-triyl triacetate to produce (2R,3R,4S,5R,6R)-2-(acetoxymethyl)-6-(3-((4-(difluoromethyl)phenyl)(hydroxy)methyl)-4-fluoro-1H-indol-1-yl)tetrahydro-2H-pyran-3,4,5-triyl triacetate, 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"
    ]
}
