How is 2-Methyl-2-propanyl [(3S,4R)-4-fluoro-3-pyrrolidinyl]carbamate (CAS: 1033718-89-6) typically synthesized?

This compound can be synthesized via a multi-step process involving the protection of an amine, introduction of the fluorine substituent, and subsequent carbamoylation. Commonly used reagents include fluoroacetic acid and a suitable carbonylating agent like carbonyldiimidazole. The reaction proceeds with good selectivity and yields up to 85% depending on the specific method employed.
