Reaction Steps

17 μl propionic acid are placed in 800 μl dimethylsulphoxide, and 78 μl diisopropylethylamine and 94 mg O-(7-azabenzotriazol-1-yl-)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) are added. The mixture is stirred for 0.3 hours at ambient temperature, then a solution of 100 mg C—((S)-1-{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), in 700 μl dimethylsulphoxide is added. The reaction mixture is stirred for 15 hours at ambient temperature and then combined with water and dichloromethane. The organic phase is dried and evaporated to dryness. The product is purified by preparative HPLC (method A). 84 mg of the product are obtained as an oil. Analytical HPLC-MS (method D): RT=1.19 min.
