Abstract
A novel synthesis of pyrazolo[1,5-a]pyrimidine derivatives 4,5 and 9 bearing sulfonamide moieties from the reaction of aminopyrazoles 1 with [bis(methy1sulfanyl)methylidene]malononitrile 2, [arylamino(methylsulfanyl)methylidene]malonoNtrile 6 and ethyl [bis(methylsulfanyl)methylidene]cyano acetate 7 is reported.Keywords
