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
