Using 2-(tributylstannyl)pyrazine, 2-(1-(2-(7-chloro-1H-pyrrolo[3,2-b]pyridin-3-yl)-2-oxoacetyl)piperidin-4-ylidene)-2-phenylacetonitrile to produce 2-(1-(2-oxo-2-(7-(pyrazin-2-yl)-1H-pyrrolo[3,2-b]pyridin-3-yl)acetyl)piperidin-4-ylidene)-2-phenylacetonitrile, 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"
    ]
}
