Using tert-butyl (2-oxoethyl)carbamate, methyl (R)-14-cyclohexyl-7-(methylamino)-7,8-dihydro-6H-benzo[2,3][1,5]oxazocino[5,4-a]indole-11-carboxylate to produce methyl (R)-7-((2-((tert-butoxycarbonyl)amino)ethyl)(methyl)amino)-14-cyclohexyl-7,8-dihydro-6H-benzo[2,3][1,5]oxazocino[5,4-a]indole-11-carboxylate, 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"
    ]
}
