59.8 mg 3-{1-[5-oxo-4-(tetrahydropyran-4-ylamino)-6,7-dihydro-5H-5λ4-thieno[3,2-d]pyrimidin-2-yl]-piperidin-4-yl}-benzoic acid are placed in 2.3 ml dimethylformamide, then 91 l diisopropylethylamine and 60 mg O-(7-azabenzotriazol-1-yl-)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) are added. After 15 min a mixture of 15.5 mg cyclopropylmethylamine hydrochloride in 300 l dimethylformamide is added. The reaction mixture is stirred at ambient temperature until there is no further reaction, and the product is purified directly by preparative HPLC (method B). 50 mg Example 249 are obtained as a solid. Analytical HPLC-MS (method D): RT=1.05 min.
