[0151] Step A: Benzo[d]iso evil Azol-3-yl-phenylcarbamate Benzo[d]isoxazol-3-ylamide (3.0g) and ClCO 2 Ph (0.94mL) in dry CH 3 The mixture in CN (30 mL) was stirred at 70 °C for 23 hours. The reaction mixture was poured into deionized water, stirred for 30 minutes and filtered. The isolated solid was rinsed thoroughly with water and dried under high vacuum to afford 1.90 g (100%) of the title compound. MS: 255.1.

Abstract
Certain heteroaryl-substituted piperidinyl and piperazinyl urea compounds are described, which are useful as FAAH inhibitors. Such compounds may be used in pharmaceutical compositions and methods forthe treatment of disease states, disorders, and conditions mediated by fatty acid amide hydrolase (FAAH) activity, such as anxiety, pain, inflammation, sleep disorders, eating disorders, insulin resistance, diabetes, osteoporosis, and movement disorders (e.g., multiple sclerosis).
Description
technical field [0001] The present invention relates to certain heteroaryl-substituted piperidinyl urea and piperazinyl urea compounds, pharmaceutical compositions containing them and their use in the treatment of fatty acids mediated by fatty acid amide hydrolase (FAAH) activity methods for disease states, disorders and conditions. Background technique [0002] The medicinal benefits of the cannabis plant have been known for centuries. The main bioactive component of cannabis is Δ 9 - Tetrahydro-cannabinol (THC). The discovery of THC eventually led to the identification of two endocannabinoid receptors responsible for its pharmacological effects, known as CB 1 and CB 2 (Goya, Exp. Opin. Ther. Patents 2000, 10, 1529). These findings not only established THC's site of action, but also inspired the search for endogenous agonists, or "endocannabinoids," of these receptors. The first endocannabinoid identified was the fatty acid amide anandamide (AEA). AEA itself induces ...
