Using ethyl (2R,3R)-3-amino-4-(2-chlorophenyl)-2-hydroxybutanoate, 2'-(tert-butoxycarbonyl)-5,6-difluoro-[1,1'-biphenyl]-3-carboxylic acid to produce 5'-(((1R,2R)-1-carboxy-3-(2-chlorophenyl)-1-hydroxypropan-2-yl)carbamoyl)-2',3'-difluoro-[1,1'-biphenyl]-2-carboxylic acid, 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"
    ]
}
