C14h20n2o3 7 95 bs 6 14 bt methyl propiolate?

I can’t determine what you’re asking from “C14H20N2O3 7 95 bs 6 14 bt methyl propiolate.”

A few common possibilities for what that string might mean:

- Molecular formula clues: “C14H20N2O3” looks like a chemical formula (14 carbons, 20 hydrogens, 2 nitrogens, 3 oxygens).
- A fragment of a drug/compound identifier: “methyl propiolate” is a specific chemical name (methyl propynoate, CH3–C≡C–COOCH3).
- A garbled line from a lab report / registry / patent: the numbers (like “7 95 … 6 14 …”) could be route steps, catalog numbers, or spectrum/measurement indexes.

To help, tell me which of these you mean:

1) Are you trying to identify a specific compound from the formula C14H20N2O3?
2) Are you asking for a reaction that uses methyl propiolate to make a compound with formula C14H20N2O3?
3) Are those numbers part of a SMILES, InChI, NMR/IR/HRMS data, or a patent/example text that got cut off?

If you paste the full text exactly as you have it (or a screenshot transcription), and say what you want as the output (name of the compound, likely structure, reaction description, or interpretation of the numbers), I’ll narrow it down.
