Using cyanic bromide, (S)-N-((1H-tetrazol-5-yl)methyl)-N,4-dicyclohexyl-4-(((5-nitro-2-phenoxypyridin-4-yl)methyl)amino)butanamide to produce (S)-N-((1H-tetrazol-5-yl)methyl)-4-(2-amino-6-phenoxypyrido[3,4-d]pyrimidin-3(4H)-yl)-N,4-dicyclohexylbutanamide, 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"
    ]
}
