Using ((R)-2-((tert-butoxycarbonyl)amino)-2-phenylacetyl)-L-proline, 2-bromoimidazo[2,1-b]thiazol-6-amine to produce tert-butyl ((S)-2-((R)-2-((2-bromoimidazo[2,1-b]thiazol-6-yl)carbamoyl)pyrrolidin-1-yl)-2-oxo-1-phenylethyl)carbamate, 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"
