Reaction Steps

100 mg C—((S)—-{2-[4-(4-chloro-phenyl)-piperazin-1-yl]-5-oxo-6,7-dihydro-5H-5λ4-thieno[3,2-d]pyrimidin-4-yl}-pyrrolidin-2-yl)-methylamine trifluoroacetate, Diastereomer 2 (Example 226) (see scheme 3, 3.17.2) are placed in 2 ml dichloromethane. While cooling with the ice bath 38 μl triethylamine and 28 μl 4-morpholinecarbonyl chloride are added. The reaction mixture is stirred for 12 hours at ambient temperature and then mixed with water. The organic phase is dried and evaporated to dryness. 121 mg of the product are obtained as a solid. Analytical HPLC-MS (method D): RT=1.18 min.
