Embodiment 1
[0198] N-(3-((2-((4-(1-acetylpiperidin-4-yl)oxy)-2-methoxyphenyl)amino)-5-(trifluoromethyl)pyrim Pyridine-4-yl)amino)phenyl)acrylamide
[0199]
[0200] step 1:
[0201]
[0202] tert-butyl 4-hydroxypiperidine-1-carboxylate (4.70g, 23.3mmol), 4-fluoro-2-methoxynitrobenzene (2g, 11.6mmol), tetrabutylammonium bromide (0.754g, 2.34 mmol) and aqueous potassium hydroxide solution were stirred overnight at 60°C in toluene. The reaction mixture was brought to room temperature, diluted with water and extracted with ethyl acetate. The collected organic phase was dried and purified by column chromatography to obtain yellow oily product tert-butyl 4-(3-methoxy-4-nitrophenoxy)piperidine-1-carboxylate (3.73 g, 91% yield) . 1 H NMR (300MHz, CDCl 3 )(δ / ppm): 8.01(d, J=9.6Hz, 1H), 6.56-6.49(m, 2H), 4.61-4.57(m, 1H), 3.96(s, 3H), 3.75-3.67(m, 2H), 3.44-3.36 (m, 2H), 2.01-1.94 (m, 2H), 1.84-1.76 (m, 2H), 1.45 (s, 9H). LC-MS(APCI): m / z=353.2(M+1) + , Purity: 97.6%.

Embodiment 2
[0222] N-(3-((2-((4-(1-acetylpiperidin-4-yl)amino)-2-methoxyphenyl)amino)-5-(trifluoromethyl)pyrim Pyridine-4-yl)amino)phenyl)acrylamide
[0223]
[0224] step 1:
[0225]
[0226] The synthesis procedure was the same as step 1 of Example 1 to obtain the product tert-butyl 4-(3-methoxy-4-nitrophenylamino)piperidine-1-carboxylate (0.96 g, yield: 93.6%). LC-MS(APCI): m / z=352(M+1) + , Purity: 95.1%.
[0227] Step 2:
[0228]
[0229] The synthesis steps were the same as in Example 1, step 2, to obtain dark blue oily product 4-(4-amino-3-methoxyphenylamino)piperidine-1-carboxylic acid tert-butyl ester (0.19g, yield: 91%) , used directly in the next step.
[0230] Step 3:
[0231]
[0232] The synthesis procedure is the same as that of Example 1 step 3, and the white solid product 4-((4-((4-(3-acrylamide phenylamino)-5-trifluoromethylpyrimidin-2-yl)amino-3-methyl Oxyphenyl)amino)piperidine-1-carboxylic acid tert-butyl ester (89 mg, yield: 54.6%).

Embodiment 3
[0240] N-(3-((2-((4-(1-acetyl-1,2,3,6-tetrahydropyridin-4-yl)-2-methoxyphenyl)amino)-5- (Trifluoromethyl)pyrimidin-4-yl)amino)phenyl)acrylamide
[0241]
[0242] step 1:
[0243]
[0244] PdCl 2 (dppf) 2 (422mg, 0.052mmol) was added to 4-bromo-2-methoxynitrobenzene (2.0g, 8.62mmol), 4-(4,4,5,5-tetramethyl-1,3,2-di Oxaborolan-2-yl)-1,2,5,6-tetrahydropyridine-1-carboxylic acid tert-butyl ester and K 2 CO 3 (3.57g, 19.38mmol) in 1,4-dioxane (40mL), heated to 90°C under nitrogen atmosphere and stirred for 14h. Poured into water (150mL), extracted with dichloromethane (50mL x 3), spin-dried, and passed through the column to obtain the yellow solid product 4-(3-methoxy-4-nitrophenyl)-1,2,5,6 - tert-butyl tetrahydropyridine-1-carboxylate (1.6 g, yield: 56%). 1 HNMR (300MHz, CDCl 3 )(δ / ppm): 7.87(d, J=9Hz, 1H), 7.03-7.00(m, 2H), 6.19(s, 1H), 4.13(t, J=3Hz, 2H), 3.99(s, 3H ), 3.67(t, J=6Hz, 2H), 1.53(s, 9H). LC-MS(APCI): m / z=335.2(M+1) + , Purity: 94.6%.
