Using 1-bromopropane, 2-((5-chloro-1H-indol-3-yl)methyl)-5-methyl-3-(1-methyl-1H-imidazol-2-yl)-2,7-dihydro-4H-pyrazolo[3,4-d]pyrimidine-4,6(5H)-dione to produce 2-((5-chloro-1H-indol-3-yl)methyl)-5-methyl-3-(1-methyl-1H-imidazol-2-yl)-7-propyl-2,7-dihydro-4H-pyrazolo[3,4-d]pyrimidine-4,6(5H)-dione, 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",
