Using C[S+](C)(C)=O, methyl (E)-3-ethyl-4-oxo-2-styryl-4H-pyrido[1,2-a]pyrimidine-7-carboxylate to produce methyl (E)-6-ethyl-7-oxo-5-styryl-1,8a-dihydrocyclopropa[5,6]pyrido[1,2-a]pyrimidine-1a(7H)-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",
