Embodiment 1
[0297] Example 14-((3R,4R)-4-methyl-3-(methyl(7H-pyrrolo[2,3-d]pyrimidin-4-yl)amine)piperidine-1-carbonyl)benzonitrile
[0298]
[0299] Step 1: Synthesis of compound 4-chloro-7-p-toluenesulfonyl-7H-pyrrolo[2,3-d]pyrimidine
[0300] Dissolve 4-chloropyrrolo[2,3-d]pyrimidine (5.00g, 32.56mmol) and p-toluenesulfonic acid chloride (6.83g, 35.82mmol) in acetone (50mL), and add to the reaction solution at 0°C A solution of sodium hydroxide (1.56g, 39.07mmol) in water (20mL) was slowly added dropwise to the mixture, and after the addition was completed, the reaction was stirred at room temperature for 8 hours. After the reaction was completed, the reaction solution was filtered, and the filter cake was washed with a mixed solvent of acetone / water (10 mL, v / v=1 / 1) and then dried to obtain 9.39 g of a white solid with a yield of 93.71%.

[0315] Example 23-((3R,4R)-4-methyl-3-(methyl(7H-pyrrolo[2,3-d]pyrimidin-4-yl)amine)piperidine-1-carbonyl)benzenesulfonate Amide
[0316]
[0317] N-Methyl-N-((3R,4R)-4-methylpiperidin-3-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (114.0mg, 0.46mmol) , m-sulfonamide benzoic acid (185.1mg, 0.92mmol) and 2-(7-azobenzotriazole)-N,N,N',N'-tetramethyluronium hexafluorophosphate (349.8mg, 0.92mmol) was dissolved in DMF (8mL), then N,N-diisopropylethylamine (237.8mg, 1.84mmol) was added, and the mixture was stirred at room temperature for 2 hours. After completion of the reaction, water (20 mL) was added to the reaction solution to quench the reaction, extracted with ethyl acetate (60 mL), and the combined organic phase was washed with anhydrous Na 2 SO 4 Dry, filter, and concentrate under reduced pressure, and the resulting residue is subjected to silica gel column chromatography (eluent: CH 2 Cl 2 / MeOH (v / v)=10 / 1), purified to obtain 46.0 mg of white solid, yield: 23.34%.

[0320] Example 31-((3R,4R)-4-methyl-3-(methyl(7H-pyrrolo[2,3-d]pyrimidin-4-yl)amine)piperidine-1-carbonyl)-3 -Cyanoazetidine
[0321]
[0322] 3-cyanoazetidine hydrochloride (162.4mg, 1.377mmol) and N,N-diisopropylethylamine (389.0mg, 3.01mmol) were added to triphosgene (69.6mg, 0.51mmol) in di Methyl chloride (12mL) solution, stirred at room temperature for 1h, then added N-methyl-N-((3R,4R)-4-methylpiperidin-3-yl)-7H-pyrrolo[2,3 -d] Pyrimidin-4-amine (336mg, 1.37mmol), then slowly drop N,N-diisopropylethylamine (195.2mg, 1.51mmol) in dichloromethane (8mL) solution, react at room temperature for 48h. After completion of the reaction, it was concentrated under reduced pressure, and the obtained residue was subjected to silica gel column chromatography (eluent: CH 2 Cl 2 / CH 3 OH (v / v)=14 / 1), purified to obtain 47.7 mg of white solid, yield: 9.85%.
