Procedure

0.30 g (0.5 mmol) 4-ethoxy-9-trifluoromethyl-7-(4-iodo-phenyl)-2-piperazin-1-yl-pyrido[3′,2′:4,5]thieno[3,2-d]pyrimidine, 0.14 g (2.1 mmol) pyrazole, 0.22 g (1.0 mmol) potassiumphosphate-tribasic, 0.06 g (0.3 mmol) copper(I)-iodide and 0.014 g (0.1 mmol) (1R,2R)—N,N′-dimethyl-1,2-cyclohexanediamine in 5 ml N,N-dimethylformamide (dry) are stirred at 110° C. under nitrogen atmosphere for 24 h. The solvent is removed in vacuo and the residue is suspended in 20 ml water, sucked off, washed with 100 ml water and suck dried. Following purification by means of flash chromatography (methanol/dichloromethane 1:10) 0.04 g (15%) 4-ethoxy-9-trifluoromethyl-2-piperazin-1-yl-7-(4-(1H-pyrazol-1-yl)-phenyl)-pyrido[3′,2′:4,5]thieno-[3,2-d]pyrimidine is obtained.
