Using triethyl orthoformate, (S)-3-fluoro-N2-(1-(5-fluoropyrimidin-2-yl)ethyl)-N6-(5-methyl-1H-pyrazol-3-yl)-5-nitropyridine-2,6-diamine to produce (S)-6-fluoro-N-(1-(5-fluoropyrimidin-2-yl)ethyl)-3-(5-methyl-1H-pyrazol-3-yl)-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": [
