[0018] The starting materials used in the preparation of the compounds of the present invention are known, can be prepared according to known methods, or are commercially available.
[0019] The invention also relates to novel intermediates and / or starting materials. Particular preference is given to reaction conditions and novel intermediates which are the same or similar to those mentioned in the examples.
[0020] Both intermediates and final products can be worked up and / or purified according to conventional methods including pH adjustment, extraction, filtration, drying, concentration, chromatography, trituration, crystallization, and the like.
[0021] In addition, the compounds of the present invention can be prepared by various methods known in the art or variations on the methods described herein.
[0022] The following examples are only used to illustrate the present invention and do not limit the present invention in any way.
Embodiment 1
[0023] Example 1 N-(4-(7-cyclopentyl-6-(dimethylcarbamoyl)-7H-pyrrolo[2,3-d]pyrimidin-2-yl)amino)phenyl)-N -Synthesis of phenylcyclopropane-1,1-dicarboxamide
[0024]
[0025] Step 1.1: Preparation of 1-(phenylcarbamoyl)cyclopropane-1-carboxylic acid
[0026]
[0027] Cyclopropane-1,1-dicarboxylic acid (13.01 g, 100 mmol) was dissolved in 150 mL of isopropyl acetate and cooled to 0°C, then thionyl chloride (12.5 g, 105 mmol) was added dropwise. After the dropwise addition was completed, the mixture was raised to room temperature and stirred for 6 hours. A solution of aniline (110 mmol) and triethylamine (15.29 mL, 110 mmol) in isopropyl acetate (40 mL) was added dropwise for about 1 hour, and stirring was continued for 2 hours. The reaction solution was diluted with ethyl acetate (500 mL), washed with 1 N hydrochloric acid and saturated sodium chloride, dried over anhydrous magnesium sulfate and concentrated to obtain a crude product. Suspend the crude product in hept...
Embodiment 2
[0034] Example 2 N-(4-(7-cyclopentyl-6-(dimethylcarbamoyl)-7H-pyrrolo[2,3-d]pyrimidin-2-yl)amino)phenyl)-N Synthesis of -(2-fluorophenyl)cyclopropane-1,1-dicarboxamide
[0035]
[0036] Step 2.1: 1 - Synthesis of ((2-fluorophenyl)carbamoyl)cyclopropane-1-carboxylic acid
[0037]
[0038] The method is the same as step 1.1, white solid, yield: 45%, 1 H NMR (400 MHz, DMSO-d 6 ) δ 13.51 (s,1H), 11.27 (s, 1H), 8.15 (td, J = 8.0, 2.0 Hz, 1H), 7.27 (ddd, J = 11.4, 7.9,1.8 Hz, 1H), 7.13 (tdd, J = 13.3, 7.7, 3.7 Hz, 2H), 1.56 (h, J = 4.0 Hz, 4H).
[0039] Step 2.2: Synthesis of N-(4-aminophenyl)-N-(2-fluorophenyl)cyclopropane-1,1-dicarboxamide
[0040]
[0041] The method is the same as step 1.2, brown solid, yield: 54%. 1 H NMR (400 MHz, DMSO-d 6 ) δ 11.16 (s,1H), 9.40 (s, 1H), 8.04 (td, J = 7.8, 2.4 Hz, 1H), 7.33 – 7.22 (m, 1H), 7.20– 7.09 (m, 4H), 6.53 ( d, J = 8.4 Hz, 2H), 4.99 (s, 2H), 1.66 – 1.53 (m, 4H); 13 C NMR (101 MHz, DMSO) Δ 170.14, 169.01, 152.43, 146.32...
