Versuchsvorschrift
A mixture of 2-chloro-N-(5-cyclopropyl-1H-pyrazol-3-yl)-5-((trimethylsilyl)ethynyl) pyrimidin-4-amine (200 mg, 0.6 mmol, 1.0 eq), piperidine (102.7 mg, 1.2 mmol, 2.0 eq) in iPrOH (4 ml) was stirred at room temperature for 2 h. Then the mixture was washed with water, extracted with EtOAc, dried (Na2SO4). EtOAc was removed by evaporation and the residue was recrystalized by PE to give compound N-(5-cyclopropyl-1H-pyrazol-3-yl)-2-(piperidin-1-yl)-5-((trimethylsilyl)ethynyl)pyrimidin-4-amine (101 mg, 44.3%).
