Transition-metal-free synthesis of primary to tertiary carboxamides: A quick access to prodrug-pyrazinecarboxamide
摘要:
One-pot expedient and direct carbamoylation of heterocyclics is described. The transformation is realized via direct dehydrogenative aminocarbonylation of heterocyclic compounds under transition-metal-free conditions. This method is regioselective and the protocol is proved to be scalable on a gram scale. Further, the therapeutically useful antitubercular agent pyrazinecarboxamide is successfully synthesized by employing this protocol. (C) 2017 Elsevier Ltd. All rights reserved.

The present invention is directed to a composition useful for the treatment of a FAAH mediated disease, disorder or conditions comprising a FAAH inhibitor and a second activation, comprising a selected imidazole or oxazole FAAH inhibitor and a second active agent. The compositions will be useful in the treatment of a wide range of disease, disorder, or conditions including osteoarthritis, rheumatoid arthritis, diabetic neuropathy, postherpetic neuralgia, skeletomuscular pain, and fibromyalgia, as well as acute pain, migraine, sleep disorder, Alzheimer disease, and Parkinson's disease. In another aspect the invention discloses herein is directed to compositions useful in the treatment of neuropathic and nociceptive pain, said compositions comprising etoricoxib.
