Using dihydro-2H-pyran-3(4H)-one, 2-(6-iodobenzofuran-3-yl)ethan-1-amine to produce 7-iodo-3,4,5',6'-tetrahydro-2H,2'H,4'H-spiro[benzofuro[2,3-c]pyridine-1,3'-pyran], 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"
    ]
