[0129] Example 1: 5-chloro-N4-(2-(isopropylsulfonyl)phenyl)-N2-(2-methoxy-4-(1,2,3,6-tetrahydropyridine-4- Preparation of yl)phenyl)pyrimidine-2,4-diamine
[0130] Step 1: 4-(4-((5-Chloro-4-((2-(isopropylsulfonyl)phenyl)amino)pyrimidin-2-yl)amino)-3-methoxyphenyl)- Preparation of tert-butyl 5,6-dihydropyridine-1(2H)-carboxylate
[0131]
[0132] 2,5-dichloro-N-(2-(isopropylsulfonyl)phenyl)pyrimidin-4-amine (1.6g, 4.6mmol) was dissolved in 25ml of THF, and 4-(4- Amino-3-methoxyphenyl)-5,6-dihydropyridine-1(2H)-carboxylic acid tert-butyl ester (1.4 g, 4.6 mmol). Add 4,5-bisdiphenylphosphine-9,9-dimethylxanthene to it in sequence (266mg, 0.46mmol) and Cs 2 CO 3 (4.5 g, 13.8 mmol), followed by degassing by filling with nitrogen. Add Pd(OAc) to it 2 (51.6 mg, 0.23 mmol). After filling with nitrogen, the reaction mixture was stirred at 130 °C for 18 hours. After the reaction was complete, the mixture was then washed with EA / H 2 O extraction. The organic layer was wash...

[0139] Step 1: 4-(4-((5-Chloro-4-((2-(isopropylsulfonyl)phenyl)amino)pyrimidin-2-yl)amino)-5-isopropoxy-2- Preparation of tert-butyl methylphenyl)-5,6-dihydropyridine-1(2H)-carboxylate
[0140]
[0141] 2,5-dichloro-N-(2-(isopropylsulfonyl)phenyl)pyrimidin-4-amine (1 g, 2.88 mmol) was dissolved in 20 ml of THF, and 4-(4-amino - tert-butyl 5-isopropoxy-2-methylphenyl)-5,6-dihydropyridine-1(2H)-carboxylate (955 mg, 2.88 mmol). Add 4,5-bisdiphenylphosphine-9,9-dimethylxanthene (167 mg, 0.288 mmol) and Cs in sequence 2 CO 3 (2.8 g, 8.64 mmol), followed by degassing by filling with nitrogen. Add Pd(OAc) to it 2 (32 mg, 0.144 mmol). After filling with nitrogen, the reaction mixture was stirred at 130 °C for 18 hours. After the reaction was complete, the mixture was then washed with EA / H 2 O extraction. Th...
