Vorschrift

1.09 g (2-chloro-6,7-dihydro-thieno[3,2-d]pyrimidin-4-yl)-(3-morpholin-4-ylmethyl-phenyl)-amine, 1.77 g 1-(4-chloro-phenyl)-piperazine and 1.03 ml diisopropylethylamine are placed in 12 ml dioxane, then heated in the microwave for 1 hour at 160° C. Then water is added and the mixture is extracted with dichloromethane. The organic phase is separated off using a phase transfer cartridge and evaporated to dryness. The residue is crystallised with methanol. 1.17 g of the product are obtained as a powder (m.p 177°-178° C.).
