Using N1,N3-diphenylpropane-1,3-diimine, 1-(5-carboxypentyl)-4,6-difluoro-2,3,3-trimethyl-3H-indol-1-ium to produce 6-((E)-4,6-difluoro-3,3-dimethyl-2-((2E,4E)-4-(phenylimino)but-2-en-1-ylidene)indolin-1-yl)hexanoic 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"
    ]
