- STUDIES ON AS-TRIAZINE DERIVATIVES. IX. SYNTHESIS OF 5-SUBSTITUTED 1,2,4-TRIAZINE DERIVATIVES THROUGH AN ADDITION REACTION AND SUBSEQUENT OXIDATION
-
The addition reactions of various nucleophiles to 6-methyl-3-phenyl-1,2,4-triazine (1) were investigated and a practical preparation of 1 was developed.The reactions showed many similarities to those of quinazoline (at the 4-position) and acridine (at the

-
Dehydroxy-chlorination of 6-methyl-3-phenyl (3a), and 3,6-diphenyl-5-oxo-2,5-dihydro-1,2,4-triazine (3b) afforded the corresponding 5-chloro-1,2,4-triazines (4a,b).The chloro-1,2,4-triazines (4a,b) treated with sodium alkoxides or amines to give the 5-alk

The reaction of 5-chloro-6-methyl-3-phenyl-1,2,4-triazine (4a) with ethylidenetriphenylphosphorane followed by the hydrolysis of the resulting as-triazinylphosphorane afforded 5-ethyl-6-methyl-3-phenyl-1,2,4-triazine (6a) in 88 percent yield.The condensat
