Using perbromomethane, dimethyl 3,3'-(((((5-(hydroxymethyl)-1,3-phenylene)bis(oxy))bis(octane-8,1-diyl))bis(oxy))bis(3-methoxy-4,1-phenylene))(2E,2'E)-diacrylate to produce dimethyl 3,3'-(((((5-(bromomethyl)-1,3-phenylene)bis(oxy))bis(octane-8,1-diyl))bis(oxy))bis(3-methoxy-4,1-phenylene))(2E,2'E)-diacrylate, please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
