Using (3aR,5R,6S,6aR)-6-(benzyloxy)-5-((benzyloxy)methyl)-5-(difluoromethyl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxole, aceticanhydride to produce (3R,4S,5R)-4-(benzyloxy)-5-((benzyloxy)methyl)-5-(difluoromethyl)tetrahydrofuran-2,3-diyl diacetate, 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",

        "Cl"
    ]
}
