Using N-(3-bromopyridin-2-yl)-5-(((4-methoxybenzyl)oxy)methyl)-N-((2-(trimethylsilyl)ethoxy)methyl)furo[2,3-b]pyridine-2-carboxamide to produce 5-(((4-methoxybenzyl)oxy)methyl)-1'-((2-(trimethylsilyl)ethoxy)methyl)-3H-spiro[furo[2,3-b]pyridine-2,3'-pyrrolo[2,3-b]pyridin]-2'(1'H)-one, 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"
    ]
}
