860 mg (2.75 mmol) of methyl 3-[5-(4-methylpiperazin-1-yl)pyrimidin-2-yl]-benzoate are dissolved in 16 ml of THF, and 13.8 ml (13.8 mmol) of 1 M diisobutylaluminium hydride in THF are added dropwise at room temperature, and the reaction mixture is stirred at room temperature for 1 h. A further 13.8 ml 13 (13.8 mmol) of 1 M diisobutylaluminium hydride in THF are added dropwise, and the reaction mixture is stirred at room temperature for 1 h. 3 ml of saturated sodium sulfate solution are added to the reaction mixture with ice-cooling. Dichloromethane is added to the gelatinous mixture, which is then stirred for 30 min and filtered. The filtrate is dried over sodium sulfate and evaporated.
