Abstract
We have studied the reaction of 5-amino-3-phenylpyrazole with chalcones which takes place with the formation of arylsubstituted forms of dihydropyrazolo[1,5-a]pyrimidine and have discussed a possible mechanism for the reaction. Dehydrogenation of the compounds prepared has been effected using N-bromosucciniimide.
