Using prop-1-en-2-yl (3,3-dimethylbutyl)carbamate, 6-(5-amino-2,4-difluorophenyl)-N-methylpyrido[2,3-d]pyrimidin-2-amine to produce 1-(2,4-difluoro-5-(2-(methylamino)pyrido[2,3-d]pyrimidin-6-yl)phenyl)-3-(3,3-dimethylbutyl)urea, 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"
    ]
}
