The invention encompasses pyrazolo[1,5-a]pyrimidine derivatives which selectively inhibit microtubule affinity regulating kinase (MARK) and are therefore useful for the treatment or prevention of Alzheimer's disease. Pharmaceutical compositions and methods of use are also included.

1-dioxide in good yields. The reaction of 3-chloro- and 3-bromo-2,5-dimethylthiophene-1, 1-dioxide with piperidine, pyrrolidine and morpholine at 100 °C intoluene on the other hand gave only one of the four possible isomeric dialkylaminomethyl-substituted hatobutadienes as main products and dialkylamino-substituted cis-2,3-dihydrothiophene-1,1-dioxides as by-products. Possible reaction paths are discussed.
