Using 3-(((benzyloxy)carbonyl)(1,3-dimethyl-2,4-dioxo-5-phenyl-1,2,3,4-tetrahydro-6H-pyrrolo[3,4-d]pyrimidin-6-yl)amino)propanoic acid to produce 1,3-dimethyl-5-phenyl-8,9-dihydropyrimido[4',5':3,4]pyrrolo[1,2-b]pyridazine-2,4,10(1H,3H,7H)-trione, 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",
