    摘要: DISCLOSED ARE COMPOUNDS OF THE CLASS OF 1,2,3-BENZOTRIAZIN-4(3H)-ONES WHICH ARE SUBSTITUTED AT THE 3-POSITION AND WHICH ARE SUBSTITUTED AT LEAST TWO OF THE 6, 7 AND 8-POSITIONS BY ALKOXY OR BY AN ADJACENT METHYLENEDIOXY, E.G. 6,7-DIMETHOXY-3-(3 - MORPHOLINOPROPYLAMINO)-1,2,3BENZOTRIAZIN-4(3H)-ONE. THE COMPOUNDS HAVE PHARMACOLOGICAL ACTIVITY IN ANIMALS, E.G., ANTI-INFLAMMATORY ACTIVITY. THE COMPOUNDS MAY BE PREPARED, FOR EXAMPLE, BY ALKYLATION OF THE CORRESPONDING 3-UNSUBSTITUTED COMPOUNDS AND BY REACTION OF AN APPROPRIATELY DISUBSTITUTED ANTHRANIL AMIDE WITH SODIUM NITRITE AND A STRONG INORGANIC ACID, E.G., SULFURIC ACID.
