Using tert-butyl (S)-(5-amino-1-hydroxypentan-2-yl)carbamate, (S)-2-(((benzyloxy)carbonyl)amino)-5-((tert-butoxycarbonyl)amino)pentanoic acid to produce benzyl tert-butyl ((S)-5-(((S)-4-((tert-butoxycarbonyl)amino)-5-hydroxypentyl)amino)-5-oxopentane-1,4-diyl)dicarbamate, 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"
    ]
}
