Eingegangen am 16. Juli 1986 New 3-(pyridin-6-yl) pyraolo [ 1,5-u]pyrimidines were synthesized from (pyridin-6-y1)malonodinitrile 58, ethyl (pyridin-6-y1)cyanoacetate 5b and (pyridin-6-y1)benzoylacetonitrile 5c. Compounds 58-c were obtained from the 4,4,4-trichlorobut-2-enenitriles 2 and 1-pheny1et
Thiazolylcyanothioacetanilides react with โฃ-haloketones and haloesters to give the corresponding thiophene or thiazole derivatives according to the reaction conditions. Pyrazolo [1,5-a]pyrimidines and pyrazolo [5,1-c]triazines were synthesized by reaction of 3-amino-4-(4ะ-arylthiazol-2ะ-yl)-5-phenyl
