Provided is an agent for treating or preventing urinary frequency, urinary urgency and urinary, incontinence which are associated with overactive bladder, a lower urinary tract disease such as interstitial cystitis and chronic prostatitis accompanied by lower urinary tract pain, and various diseases accompanied by pain. A novel azolecarboxamide derivative in which an azole ring such as thioazole or oxazole is bonded to a benzene ring, pyridine ring or pyrimidine ring through carboxamide was confirmed to have a potent trkA receptor-inhibitory activity and found to be an agent for treating or preventing lower urinary tract disease and various diseases accompanied by pain, which is excellent in efficacy and safety, and thus the present invention was accomplished.
In one aspect, the present disclosure describes new estrogen receptor-related orphan receptor (EER) inverse agonist compounds. Also described are pharmaceutical formulations, methods of synthesis and uses thereof.

Radical C–H Arylation of Oxazoles with Aryl Iodides: dppf as an Electron-Transfer Mediator for Cs<sub>2</sub>CO<sub>3</sub>
A radical C–H arylation reaction of oxazoles with (hetero)aryl iodides using Cs2CO3 as base/electron donor and 1,1′-bis(diphenylphosphino) ferrocene (dppf) as a catalytic SET mediator is reported. The overall reaction likely follows the general base-promoted homolytic aromaticsubstitution mechanism through a radical-chain pathway. DFT calculations suggest that dppf forms a complex with CsCO3–, enhancing
报道了使用Cs 2 CO 3作为碱/电子给体和1,1'-双(二苯基膦基)二茂铁(dppf)作为催化SET介体,恶唑与(杂)芳基碘化物的自由基CH芳基化反应。整个反应可能通过自由基链途径遵循一般的碱促进的均质芳族取代机理。DFT计算表明,dppf与CsCO 3 –形成络合物,增强了SET还原能力,可从ArI生成芳基。
