4-Chloro-quinazoline-6-carbaldehyde (200 mg, 1 mmol) was dissolved in 10 ml dioxane. To this solution was added a solution of dimethylamine in water (Seq.). The mixture was stirred during 2 h at r.t. Evaporation of the solvents and remaining amine under high vacuum afforded pure 4-Dimethylamino-quinazoline-6-carbaldehyde as a yellow solid, which was used for the next step without further purification (190 mg=91%).
