반응 단계
N-(3-Ethyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-yl)-7-fluoroimidazo[1,2-a]pyridine-3-carboxamide (12 mg, 0.03 mmol; Example 74, Step A) was dissolved in toluene (0.2 mL) and 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (DMPU) (0.1 mL) and piperazine (24 mg, 0.28 mmol) was added in one portion. The mixture was heated to 105° C. and stirred for 16 hours. The crude mixture was loaded onto a Biotage 12+ C-18 samplet and purified using a gradient of 10-65% acetonitrile/water to give N-(3-ethyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-yl)-7-(piperazin-1-yl)imidazo[1,2-a]pyridine-3-carboxamide as a white solid (12 mg). MS m/z 495.3 (M+1, APCI+)
