Using 2,6-dichloro-7H-purine, (3S,4R)-3,5-bis((tert-butyldimethylsilyl)oxy)-2,2-difluoro-3,4,5-trihydroxypentanoic acid to produce (3S,4R)-3,5-bis((tert-butyldimethylsilyl)oxy)-1-(2,6-dichloro-9H-purin-9-yl)-2,2-difluoro-3,4,5-trihydroxypentan-1-one, 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"
    ]
}
