Embodiment 1
[0192] (E)-N-((3-((5-chloro-4-((naphthalen-2-yl)amino))pyrimidin-2-yl)amino)-4-methoxyphenyl)-4-( Dimethylamino)-2-butenamide (CCB118563)
[0193]
[0194] Step 1.2, 5-Dichloro-N-(naphthalen-2-yl)pyrimidin-4-amine (2)
[0195] 2,4,5-Trichloropyrimidine (6g, 32.7mmol), 2-naphthylamine (4.92g, 34.4mmol), sodium carbonate (6.94g, 65.4mmol) were dissolved in absolute ethanol (100mL) and stirred overnight at room temperature . Ice water (300 mL) was added with stirring, and a large amount of solid precipitated out. Filter under reduced pressure and dry under vacuum to obtain a brown solid (8.38 g, yield 88%).
