Using triethyl orthoformate, (R)-N6-(1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)pyrrolidin-3-yl)-N6-methylpyridine-2,3,6-triamine to produce (R)-N-(1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)pyrrolidin-3-yl)-N-methyl-3H-imidazo[4,5-b]pyridin-5-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"
    ]
}
