Versuchsvorschrift

1-(4-(4-(2-chloro-5-fluoropyrimidine-4-ylamino)-3-(difluoromethoxy)phenyl)piperazin-1-yl)ethanone (320 mg) and tert-butyl-4-(4-amino-3-methoxyphenyl)piperazin-1-carboxylate (236 mg) were dissolved in 0.08M HCl ethoxyethanol solution (7.7 ml), and stirred at 115° C. overnight. Upon completion of the reaction, the mixture was distilled under reduced pressure to remove the solvent, and the thus obtained oil was diluted with ethyl acetate. The diluted mixture was neutralized with a saturated aqueous solution of sodium bicarbonate, subjected to layer separation, and the extracted organic layer obtained as a result of layer separation was dried with sodium sulfate. The dried organic layer was distilled under reduced pressure to remove the solvent and purified by column chromatography to obtain a target compound (100 mg, 22%).
