Using aceticacid, (2R,3S)-3-amino-1-((3-ethylbenzyl)amino)-4-(3-(hexyloxy)phenyl)butan-2-ol to produce N-((2S,3R)-4-((3-ethylbenzyl)amino)-1-(3-(hexyloxy)phenyl)-3-hydroxybutan-2-yl)acetamide, 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"
    ]
}
