, p. 965 - 974 (2007/10/03)
The convergent synthesis of ethyl 5-chloro- and 5-amino-3-aryl-1,2,4-triazinecarboxylates 9a-9d and 10a-10d as well as of 5-amino-3-aryl-1,2,4-triazine-6-carboxamides 11a-11d is described. Compounds 9, 10 and 11 are powerful key compounds for cyclization reactions to the novel pyrimido[4,5-e][1,2,4]triazines 13d, 14c, 14d, 15c and 17a, 17d.
