Using (5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaene-1-thiol, ethyl 2-bromo-2-methylbutanoate to produce ethyl 2-(((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaen-1-yl)thio)-2-methylpropanoate, 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",
