PURINES, PYRIMIDINES AND CONDENSED SYSTEMS BASED ON THEM. 10. REACTIVITY OF 1,3-DIMETHYL-6-CHLOROLUMAZINE WITH RESPECT TO AMINES: COMPETITION OF AMINODECHLORINATION AND AMINODEHYDROGENATION REACTIONS

Article abstract of DOI:10.1007/BF00531478

1,3-Dimethyl-6-chlorolumazine reacts with secondary alkylamines and hydrazine to form 1,3-dimethyl-6-amino(hydrazino) derivatives in good yields.At the same time, 6-chloro-7-amino-1,3-dimethyllumazines are formed by the action of primary amines and liquid ammonia, in addition to the nucleophilic substitution products of chlorine.
