Process for synthesis of pyrazolidinone compounds |
| abstract |
A process for the synthesis of pyrazolidinone, particularly alkyl 2-(3-chloropyridin-2-yl)-5-oxo-pyrazolidine-3-carboxylate (pyrazolidinone) compound, is provided. The process is simple, economical, and produces alkyl 2-(3-chloropyridin-2-yl)-5-oxo-pyrazolidine-3-carboxylate with a comparatively high yields. |
