Using butyllithium, (2R,6R)-4-(benzyloxy)-2,6-bis((tert-butyldimethylsilyl)oxy)cyclohexan-1-one to produce (((1R,3R)-5-(benzyloxy)-2-methylenecyclohexane-1,3-diyl)bis(oxy))bis(tert-butyldimethylsilane), 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"
    ]
}
