Using hydroxide, 3a-methyl-1,2,3,3a,4,5-hexahydro-6H-pyrido[3,2,1-jk]carbazol-6-one to produce 3-(1-methyl-2,3,4,9-tetrahydro-1H-carbazol-1-yl)propanoic acid, please predict the condition, including solvent and agent in SMILES notation in json format like:

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