Using 2-(4-(6-amino-2,3-difluorophenoxy)tetrahydro-2H-pyran-4-yl)-2-(dibenzylamino)acetic acid to produce 3-(dibenzylamino)-8,9-difluoro-2',3',5',6'-tetrahydro-3H-spiro[benzo[b][1,4]oxazepine-2,4'-pyran]-4(5H)-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"
    ]
