The present invention relates to novel diarylurea derivatives useful as chloride channel blockers. In other aspects the invention relates to the use of these compounds in a method for therapy, such as for the treatment of bone metabolic diseases, diseases responsive to modulation of the mast cell or basophil activity, diseases responsive to inhibition of angiogenesis, or sickle cell anaemia, and to pharmaceutical compositions comprising the compounds of the invention.
One-step replacement of NH2 groups in ring-substitutedanilines by deuterium is reported. Approaches comprising both solid-phase and solution-phase syntheses can be used on a large variety of substrates. The method uses diazotization in a mixture of water and either dichloromethane or chloroform, which serve as a source of hydrogen. This protocol can be used as a general method for fast and easy incorporation
