Pyridazine 1-oxide, 3-methoxy-, reaction

Pyrazino[2,3-nucleophilic displacements their most common reactions were reported in CHEC-I. Some additional nucleophilic displacements of pyridazino[4,5-6]quinoxaline have been described <84JHC1271>. The oxidation of 4- -butylamino-2-methoxy-... [Pg.749]

Acetoxy - 3 - methoxy - 6( lA) - pyridazinone and 1,3- dimethoxy -6(lA)-pyridazinone are formed by the reaction of 3,6-dimethoxy-pyridazine 1-oxide with acetic anhydride. In addition, 1,3-dimethoxy-6(lA)-pyridazinone is obtained from the last-mentioned starting... [Pg.299]

Analogous reactions are known also with 4-(or 5-)methoxypyrid-azine 1 -oxides. Examples are the formation of l-methoxy-(or ethoxy-)-4(l//)-p50 idazinone (together with 4-hydroxypyridazine 1-oxide) from 4-methoxy(or ethoxy)pyridazine 1-oxide and 1,3,4-trimethoxy-6( 1 A)-pyridazinone from 3,4,6-trimethoxypyridazine 1-oxide, while 5-methoxypyridazine 1-oxide gave exclusively 2-methy l-3(2A)-pyrid-azinone 1-oxide. [Pg.299]
