Synthesis of some new pyrido[3',2':4,5]thieno[3,2-d[1,2,3-triazines with antianaphylactic activity

Some new pyrido[3',2':4,5]thieno[3,2-d]1,2,3-triazine-4(3H)-ones (C) were synthesized from 2-thioxo-1,2-dihydro-3-carbonitriles (A) via the 3-amino-thieno[2,3-b]pyridine-2-carboxamides (B). Substances of structure A were converted to 3-amino-thieno[2,3-b]
