Denitrogenative ortho-arylation, vinylation and methylation of 1,2,3-benzotriazin-4-(3H)-ones with organic boronic acids catalyzed by nickel complexes to give a wide range of o-substituted benzamides were demonstrated. Further, the catalytic reaction is successfully applied to the synthesis of the popular hypertensive drugs losartan and irbesartan in high yields. (Figure presented.).
