A series of N-[{2-(4-methylpiperidin-1-yl)-6-(trifluoromethyl)-pyridin-3-yl}methyl] N′-(6,6-fused heterocyclic) ureas have been investigated as hTRPV1 antagonists. Among them, compound 15 showed highly potent TRPV1 antagonism to capsaicin, with Ki(ant) = 0.2 nM, as well as antagonism to other activators, and it was efficacious in a pain model. A docking study of 15 with our hTRPV1 homology model indicates that there is crucial hydrogen bonding between the ring nitrogen and the receptor, contributing to its potency.

A new synthetic pathway to quinazolines is described. This new method uses hexamethylenetetramine in TFA and potassium ferricyanide in aqueous ethanolic KOH, starting from simple N-protected anilines. The method affords substituted quinazolines with high
