Using methylmagnesium(II), (2S,4R,5R)-4-((2,4-dichlorobenzyl)oxy)-5-(((2,4-dichlorobenzyl)oxy)methyl)-2-methoxydihydrofuran-3(2H)-one to produce (2S,3R,4R,5R)-4-((2,4-dichlorobenzyl)oxy)-5-(((2,4-dichlorobenzyl)oxy)methyl)-2-methoxy-3-methyltetrahydrofuran-3-ol, 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"
    ]
}
