Using (R)-N-(bis(4-methoxyphenyl)(phenyl)methyl)-6-((diphenylmethylene)amino)-5',5'-difluoro-5',6'-dihydrospiro[thiochromane-4,4'-[1,3]oxazin]-2'-amine to produce (R)-5',5'-difluoro-5',6'-dihydrospiro[thiochromane-4,4'-[1,3]oxazine]-2',6-diamine, 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"
    ]
}
