Reaction Steps

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) are placed in 2 ml dichloromethane and 30 μl phenylisocyanate are added. The reaction mixture is stirred for 4 hours at ambient temperature and then evaporated to dryness. The product is purified by preparative HPLC (method A). 64 mg of the product are obtained as a powder. Analytical HPLC-MS (method D): RT=1.33 min.
