reagent Me3SiCF2H enables multigram synthesis of difluoromethyl alcohols in good yields under mild conditions from a number of aldehydes and ketones in the presence of HMPA. This additive makes possible the previously challenging nucleophilic difluoromethylation of enolizable ketones. DMPU can be used as a non-toxic alternative to the HMPA in the difluoromethylation reaction, albeit the yields were slightly

A series of 5-arylamino-1,2,4-triazin-6(1H)-ones was synthesized and evaluated as antagonists at the corticotropin releasing factor receptor. Formation of CYP-mediated oxidative reactive metabolites previously observed in a related N-3-phenylpyrazinone structure was minimized by incorporation of the additional ring nitrogen found in the triazinones.
