Versuchsvorschrift

800 mg 2,4-dichloro-6,7-dihydro-thieno[3,2-d]pyrimidine and 800 mg D-valinamide hydrochloride are placed in 8 ml dioxane, then 2.7 ml diisopropylethylamine are added. The reaction mixture is heated to 120° C. in the microwave for 2 hours. The residue is mixed with water. The precipitate formed is suction filtered and dried. 820 mg of the product are obtained as a powder. Analytical HPLC (method B): RT=2.64 min.
