Practical Synthesis of Ethyl 3-Fluoro-1-pyrrole-2-carboxylate: A Key Fragment of a Potent Drug Candidate against Hepatitis B Virus

Abstract : We report herein the development of two efficient synthetic routes for the preparation of a key fragment required for the synthesis of potent drug candidates of Hepatitis B virus. The ethyl 3-fluoro-1-H-pyrrole-2-carboxylate scaffold was synthesized from readily available starting materials in good overall yields. The scalability of one of the developed routes was demonstrated and afforded the desired target in good yield and excellent purity (99%).
