Using diethyl oxalate, N-isopropyl-4-oxo-6-phenylhexahydropyrrolo[1,2-a]pyrazine-2(1H)-carboxamide to produce (7R,9aS)-4-hydroxy-2-isopropyl-7-phenyl-8,9,9a,10-tetrahydro-7H-pyrrolo[1',2':4,5]pyrazino[1,2-c]pyrimidine-1,3,5(2H)-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": [
