Using cyanic bromide, 4-(2-amino-5-((3R,5S)-5-(hydroxymethyl)pyrrolidin-3-yl)pyridin-3-yl)-N-((S)-1-(3-chlorophenyl)-2-hydroxyethyl)-2-fluorobenzamide to produce 4-(2-amino-5-((6R,7aS)-3-iminotetrahydro-1H,3H-pyrrolo[1,2-c]oxazol-6-yl)pyridin-3-yl)-N-((S)-1-(3-chlorophenyl)-2-hydroxyethyl)-2-fluorobenzamide, please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"

        "Cl"
    ]
}
