실험 절차

220 mg 4-chloro-2-[4-(4-chloro-phenyl)-piperazin-1-yl]-6,7-dihydro-thieno[3,2-d]pyrimidine 5-oxide (cf Example 124), 134.53 mg D-leucinol and 197.52 μl diisopropylethylamine are placed in 4 ml dioxane, heated to 120° C. in the microwave for 0.3 hours. Then the reaction mixture is mixed with water, the precipitate formed is suction filtered, washed and dried. The diastereomers are separated by preparative HPLC (method B). 43.9 mg of Diastereomer 1 (Example 53) and 46.9 mg of Diastereomer 2 (Example 69) are obtained as an oil. Analytical HPLC-MS (method B): Diastereomer 1, RT=1.86 min, Diastereomer 2, RT=1.90 min.
