Reaction Steps

Methyliodide (2 ml) was added to a solution of 6-cyano-2,2-dimethyl-4-(2-pyridyl)-2H-1,3-benzoxazine (0.20 g) in acetonitrile (14 ml) and the mixture was heated under reflux for 7 hours. After air-cooling, the solvent was distilled off under reduced pressure and the residue was crystallized from diethyl ether to obtain 2-(6-cyano-2,2-dimethyl-2H-1,3-benzoxazin-4-yl)-1-methylpyridinium iodide (0.29 g) (Compound 18).
