Using di-tert-butyl (2-(ethylamino)ethyl) phosphate, (R)-4-((4-oxo-1-(phenylthio)butan-2-yl)amino)-3-((trifluoromethyl)sulfonyl)benzenesulfonamide to produce (R)-di-tert-butyl (2-(ethyl(4-(phenylthio)-3-((4-sulfamoyl-2-((trifluoromethyl)sulfonyl)phenyl)amino)butyl)amino)ethyl) phosphate, please predict the condition, including solvent and agent in SMILES notation in json format like:

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

        "C(=NC1CCCCC1)=NC1CCCCC1",
        "Cl"
    ]
}
