A series of new 4,5-dihydropyrazolo[1,5-a]pyrimidine derivatives were synthesized by using al-dehydes, 5-amino-1H-pyrazole and malonitrile in one-pot. The structures of these compounds were characterized by IR, 1H NMR spectra and elemental analysis.

Key words: synthesis, 4,5-dihydropyrazolo[1,5-a]pyrimidine, multicomponent reaction
