The present invention is directed to triazolopyrimidine, phenylpyrimidine, pyridopyridazine, and pyridotriazine compounds which are microtubule-stabilizing compounds and their use in the treatment of neurodegenerative disorders, in particular, tauopathies, such as for example, Alzheimer's disease, frontotemporal lobar degeneration, Pick's disease, progressive supranuclear palsy (PSP), and corticobasal degeneration. In addition, the compounds of the invention may be useful for other diseases where tau pathology is a comorbidity or where microtubule function is compromised, for example, schizophrenia, Parkinson's disease (PD), PD with dementia, Lewy body disease with dementia, and amyotrophic lateral sclerosis.

radiosynthesis of 18F-labelled aryl trifluoromethyl ketones starting from widely available Weinreb amides using [18F]fluoroform is presented. The method uses potassium hexamethyldisilazane as base and delivers products in high molar activity (up to 24 GBq μmol−1) and excellent radiochemical conversions. The applicability for PET tracer synthesis is demonstrated by the radiosynthesis of ten (hetero)aryl
