Embodiment 1
[0056] 1-(4-(N-(3-(5-((1-methylpiperidin-4-yl)methoxy)pyrimidin-2-yl)phenyl)aminosulfonyl)phenyl)piperidine- 4-Formamide
[0057]
[0058] first step:
[0059] Compound 1a (57.4g, 200.0mmol), compound 1b (38.2g, 200.0mmol), K 2 CO 3 (30.4g, 220.0mmol) was dissolved in DMF (500ml), and reacted at 60°C for 8 hours, and the reaction was detected by thin layer chromatography (TLC). After the reaction was completed, part of the solvent was removed under reduced pressure, and water (500ml) was added. , was extracted twice with ethyl acetate (500ml), the organic layer was dried, concentrated and separated by chromatography to obtain 55.3g of compound 1c, with a yield of 69.4%. Compound 1c was an off-white solid.
[0060] Step two:
[0061] Compound 1c (39.8g, 100.0mmol) was dissolved in hydrogen chloride-ethyl acetate solution (500ml), stirred and reacted at 25°C for 8 hours, and detected by TLC. After the reaction was completed, the reaction was quenched with saturated sodium...
Embodiment 2
[0067] 4-(4-(N-(3-(5-((1-methylpiperidin-4-yl)methoxy)pyrimidin-2-yl)phenyl)aminosulfonyl)phenyl)piperazine- Methyl 1-formate
[0068]
[0069] Compound 1f was synthesized according to the method of the first step, the second step and the third step in Example 1.
[0070] Compound 1f (5.2g, 10.0mmol), compound 2a (1.4g, 10.0mmol), CsCO 3 (4.9g, 15.0mmol), PPh 3 (262.0mg, 1.0mmol), Pd(OAc) 2 (112 mg, 0.5 mmol) was dissolved in DMF (50 ml), heated to 100 ° C for 6 hours, after the reaction was completed, water (50 ml) was added to quench the reaction, ethyl acetate (100 ml) was extracted twice, the organic layer was dried, filtered, and column Chromatographic separation afforded 3.3 g of off-white solid, yield 56.8%, ESI(+) m / z=581.2.
Embodiment 3
[0072] 4-(4-cyanopiperidin-1-yl)-N-(3-(5-((1-methylpiperidin-4-yl)methoxy)pyrimidin-2-yl)phenyl)amino Sulfonyl)phenyl)benzenesulfonamide
[0073]
[0074] Compound 1f was synthesized according to the method of the first step, the second step and the third step in Example 1.
[0075] Compound 1f (5.2g, 10.0mmol), compound 3a (1.1g, 10.0mmol), CsCO 3 (4.9g, 15.0mmol), PPh 3 (262.0mg, 1.0mmol), Pd(OAc) 2 (112 mg, 0.5 mmol) was dissolved in DMF (50 ml), heated to 100 ° C for 6 hours, after the reaction was completed, water (50 ml) was added to quench the reaction, ethyl acetate (100 ml) was extracted twice, the organic layer was dried, filtered, and column Chromatographic separation afforded 2.8 g of off-white solid, yield 51.3%, ESI(+) m / z=547.2.
