Versuchsvorschrift

220 mg (0.57 mmol) 4-chloro-2-[4-(4-chloro-phenyl)-piperazin-1-yl]-6,7-dihydro-thieno[3,2-d]pyrimidine 5-oxide, 159.23 mg (0.69 mmol) (3R,5S)-5-hydroxymethyl-pyrrolidin-3-ol trifluoroacetate (prepared from commercial Boc-trans-4-hydroxy-L-prolinol) and 197.52 μl (1.15 mmol) diisopropylethylamine are placed in 4 ml dioxane, and heated to 120° C. in the microwave for 0.3 hours. Then the reaction mixture is combined with water and dichloromethane and extracted. The organic phase is separated off using a phase separation cartridge and evaporated to dryness. 200.3 mg of the product (75%) are obtained as a racemic mixture. Analytical HPLC-MS (method A): RT=2.26 min.
