Versuchsvorschrift

0.1 g (0.267 mmol) 4-(7-bromo-benzooxazol-2-ylamino)-2,N,N-trimethyl-benzamide and 0.17 g (0.305 mmol) 4-(2-fluoro-4-trimethylstannanyl-benzyl)-morpholine are dissolved in 2 ml 1,2-dimethoxy-ethane and a stream of argon is bubbled through the mixture in order to exclude oxygen from the reaction mixture. Tetrakis (triphenylphosphine) palladium (0.020 g, 0.016 mmol) is added and the reaction mixture is stirred at 150° C. for 1 h. After that the reaction mixture is poured on water and extracted 3× with EtOAc. The combined organic layers are washed with water and saturated NaCl solution, dried over MgSO4, filtered and the filtrate is concentrated in vacuo. The residue is purified by chromatography (silicagel, EtOAc:MeOH=95:5; column chromatography followed by thick-layer chromatography) to afford the title compound. Rt=1.67 min (Waters Symmetry C8, 2.1×50 mm, detection 210-250 nM, 5% to 100% CH3CN in H2O in 2 min+0.05% TFA, flow rate 1.0 ml/min); MS: 375 (M+1)+.
