Using n,n-dimethylformamide, N-((1R,3S,4S)-3-((tert-butyldimethylsilyl)oxy)-4-(((tert-butyldimethylsilyl)oxy)methyl)cyclopentyl)-9-methyl-8-phenyl-9H-purin-6-amine to produce N-((1R,3S,4S)-3-((tert-butyldimethylsilyl)oxy)-4-(((tert-butyldimethylsilyl)oxy)methyl)cyclopentyl)-N,9-dimethyl-8-phenyl-9H-purin-6-amine, 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"
    ]
}
