The paper describes a rapid and efficient synthesis for the isolation of protected indazolylboronic esters. These compounds were synthesized by reaction between prepared protected haloindazoles and bis(pinacolato)diboron. The effects of solvent, temperature, reaction time, and the nature of halogen atom as well as protecting group were investigated. Additionaly, these compounds reacted either with aryl halides in a Suzuki-Miyaura cross-coupling reaction or with hydrogen peroxide in a hydroxydeboronation reaction showing the potential access to new aryl and hydroxyindazole libraries.

Page/Page column 54, (2010/11/30)
Compounds of formula (I): wherein A is a 5-membered heteroaryl ring are inhibitors of p38 kinase and are useful in the treatment of conditions or disease states mediated by p38 kinase activity or mediated by cytokines produced by the activity of p38, such as rheumatoid arthritis.
