Using aceticanhydride, (S)-1-(4-fluorophenyl)-3-((2S,3R)-2-(4-hydroxyphenyl)-1-(4-iodophenyl)-4-oxoazetidin-3-yl)propyl acetate to produce 4-((2S,3R)-3-((S)-3-acetoxy-3-(4-fluorophenyl)propyl)-1-(4-iodophenyl)-4-oxoazetidin-2-yl)phenyl acetate, 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"
