Title:
Refining of the precursor compound by crystallization
Document Type and Number:
Japanese Patent JP6240507
Kind Code:
B2
Abstract:
The invention relates to a process for preparation of radiopharmaceutical precursors, and in particular protected amino acid derivatives which are used as precursors for production of radiolabelled amino acids for use in in vivo imaging procedures such as positron emission tomography (PET). Particularly, the invention relates to a process for preparation of a precursor useful in the preparation of the [18F]-1 -amino-3-fluorocyclobutanecarboxylic acid ([18F] FACBC) PET tracer.
