Number: 514/259.4
Name: Drug, bio-affecting and body treating compositions > Designated organic active ingredient containing (doai) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., o,s,se or te) or nitrogen as the only ring hetero atoms doai > Hetero ring is six-membered consisting of two nitrogens and four carbon atoms (e.g., pyridazines, etc.) > 1,3-diazines (e.g., pyrimidines, etc.) > Polycyclo ring system having 1,3-diazine as one of the cyclos > Bicyclo ring system having the 1,3-diazine as one of the cyclos > A ring nitrogen is shared by the two cyclos of the bicyclo ring system (e.g., pyrrolo [1,2-a]pyrimidine, imidazo[1,2-a]pyrimidine, etc.) > The second ring of the bicyclo ring system is six-membered, consisting of five ring carbons and the shared ring nitrogen (e.g., pyrido[1,2-a]pyrimidine, etc.)
Description: Subject matter wherein the second ring that shares a ring nitrogen with the 1,3-diazine ring is six-membered containing the shared nitrogen as its only hetero atom.
