実験手順
A suspension of 2-({2-chloro-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)-4,6-difluorobenzamide (2.71 g, 5.68 mmol), 4-[4-(1-methylethyl)-1-piperazinyl]-2-(methyloxy)aniline (2.12 g, 8.52 mmol), potassium iodide (catalytic), and sulfuric acid (2.72 ml, 51 mmols) in trifluoroethanol (150 ml) was heated at 90C for 4 hrs. The reaction was diluted with 1:1 THF:ethyl acetate (300 ml) and washed with saturated NaHCO3 (300 ml). The organic layer was removed and concentrated by rotary evaporation. The solids were then added to THF (300 ml) followed by ammonium hydroxide (300 ml) and the resulting mixture was stirred at rt overnight. Next, the crude reaction was adsorbed to silica gel and purified by LC (DCM to 5% MeOH/DCM) to afford 2,4-difluoro-6-({2-{[4-[4-(1-methylethyl)-1-piperazinyl]-2-(methyloxy)phenyl]amino}-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)benzamide (1.5 g, 38% over two steps). ESIMS (M+H)+=691.
