Using 2-mercaptoacetonitrile, (R)-4-(5-bromo-2-fluorophenyl)-3-(2,4-dimethoxybenzyl)-4-methyl-1,2,3-oxathiazolidine 2,2-dioxide to produce (R)-2-((2-(5-bromo-2-fluorophenyl)-2-((2,4-dimethoxybenzyl)amino)propyl)thio)acetonitrile, 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"
    ]
}
