title: [Synthesis of furo(2,3-b)pyridine amidines with antianaphylactic activity].
abstract: The synthesis of furo[2,3-b]pyridine formamidines (D/1-D/11, F) was realized by the reaction of the 3-amino-furo[2,3-b]pyridines C/1-C/11 and E, substituted in position 2 with a carbonyl moiety with dimethylformamide/phosphoroxide chloride or with N-formyl-piperidine or N-formyl-morpholine and phosphoroxide chloride. The acetamidines H were yielded from 4-oxo-4H-3-methyl-pyrido[3',2':4,5]furo[3,2-d]1,3-oxazines with aminoethanol. The 4-oxo-4H-3-amino-3,4-dihydro-pyrido[3',2':4,5]furo[3,2-d]pyrimidines K and M reacted with dimethylformamide/phosphoroxide chloride to give the tricyclic formamidines L and K. The described amidines showed antianaphylactic activity.
