Using benzyl 3-((7-bromo-1-(3-methoxypropyl)-3-methyl-1H-indol-6-yl)methoxy)-4-(4-(3-((2-methoxybenzyl)oxy)propoxy)phenyl)piperidine-1-carboxylate to produce 6-(((4-(4-(3-((2-methoxybenzyl)oxy)propoxy)phenyl)piperidin-3-yl)oxy)methyl)-1-(3-methoxypropyl)-3-methyl-1H-indole, 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",
