Design and synthesis of piperazinylpyrimidinones as novel selective 5-HT2C agonists
摘要:
This Letter reports the design and synthesis of several novel series of piperazinyl pyrimidinones as 5-HT2C agonists. Several of the compounds presented exhibit good in vitro potency and selectivity over the closely related 5-HT2A and 5-HT2B receptors. Compound 11 was active in in vivo models of stress urinary incontinence. (C) 2009 Elsevier Ltd. All rights reserved.

Chloroacetonitrile with malonylchloride yielded 2,3-dichloro-4,6-dihydroxypyridine together with an unexpected product, 4-chloro-2-chloromethyl-6-pyrimidone. Further examples of this new synthesis of 2-substituted 4-chloro-6-pyrimidones were obtained with fluoro- and bromo-acetonitrile, α-bromopropionitrile, and acetonitrile. Propio- and butyro-nitrile each gave a mixture of pyridine and pyrimidine
