Using carbonate, 7-bromo-1-fluoro-5-methylene-3-(neopentyloxy)-5H-chromeno[2,3-c]pyridine to produce 7-bromo-1-fluoro-3-(neopentyloxy)spiro[chromeno[2,3-c]pyridine-5,2'-oxirane], 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",
