Versuchsvorschrift

A mixture of 4-amino-6-(2-ethylbutyramido)quinazoline (5.58 g), dimethyl methoxymethylenepropanedioate (5.62 g) and N,N-dimethylformamide (22 ml) was stirred at 100° C. for 1.5 hours. After cooling to ambient temperature, water (90 ml) was added to the reaction mixture. The resulting solid was separated by filtration, washed with water and dried to give dimethyl [[6-(2-ethylbutyramido)-4-quinazolinylamino]methylene]propanedioate (4.85 g).
