Using ethylformate, (5Z,8Z,11Z,14Z)-1-bromoicosa-5,8,11,14-tetraene to produce (6Z,9Z,12Z,15Z,26Z,29Z,32Z,35Z)-hentetraconta-6,9,12,15,26,29,32,35-octaen-21-yl formate, 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"
    ]
}
