実験手順

149 mg (0.76 mmol) of 3-(6-oxo-1,6-dihydropyridazin-3-yl)benzonitrile and 256 mg (0.76 mmol) of {3-[5-(4-methylpiperazin-1-yl)pyrimidin-2-yl]phenyl}-methanol are suspended in 5 ml of DMF with 378 mg (1.13 mmol) of polymer-bound triphenylphosphine (about 3 mmol of triphenylphosphine per g) and shaken at room temperature for 30 min. 266 mg (1.134 mmol) of ditert-butyl azodicarboxylate are added. The reaction mixture is shaken at room temperature for 2 h. A further 378 mg (1.13 mmol) of polymer-bound triphenylphosphine (about 3 mmol of triphenylphosphine per g) and 266 mg (1.134 mmol) of di-tert-butyl azodicarboxylate are added, and the reaction mixture is shaken at room temperature for 2 h. The reaction mixture is filtered, the filtrate is evaporated, and the residue is purified by means of column chromatography on silica gel; yield: 59 mg of “A287”; HPLC: Rt=2.38 min (method C); LC-MS: 464 (M+H).
