Popis: | An improved synthesis of the precursor acetic acid-piperidine-4-yl ester by acetylation of 4-hydroxypiperidine hydrochloride in anhydrous chloroform was developed. A procedure for fast evaluation and characterization of products originated by acetylation of the 4-piperidinol using LC-APCI/MS with an acetonitrile-water gradient method on a Merck Purosphere RP-18 column was also developed. The highly purified precursor allowed the production of [C-11]MP4A for PET studies of acethylcholine neurotransmission system. The tracer was produced with > 98% radiochemical purity, with yields ranging 20-60% (decay-corrected) from EOB. (c) 2005 Elsevier Ltd. All rights reserved. |
