Embodiment 1
[0035] Example 1: Preparation of 4-((2-chlorothieno[3,2-d]pyrimidin-4-yl)oxy)-3,5-dimethylbenzonitrile (6)
[0036]
[0037] Weigh 4-hydroxy-3,5-dimethylbenzonitrile (1.5g, 10mmol) and potassium carbonate (1.7g, 12mmol) in 30mL DMF, stir at room temperature for 15 minutes, and then add 2,4-dichlorothiophene And [3,2-d]pyrimidine 1 (1.9g, 10mmol) was stirred at room temperature for 2h (TLC detects the completion of the reaction). When a large amount of white solid is formed, 100 mL of ice water is slowly added to it, filtered, dried in vacuum, and recrystallized from ethanol to obtain Intermediate 6. White solid, yield 93.8%, melting point 258-260°C. ESI-MS: m / z316.3[M+1] + .C 15 H 10 ClN 3 OS(315.02).
Embodiment 2
[0038] Example 2: 3,5-Dimethyl-4-((2-(piperidin-4-ylamino)thieno[3,2-d]pyrimidin-4-yl)oxy)benzonitrile (8) Preparation
[0039]
[0040] 6 (0.95g, 3.17mmol), N-Boc-4-aminopiperidine (0.83g, 3.80mmol) and potassium carbonate (0.87g, 6.33mmol) were added to 20mL of DMF, and then heated to reflux for 10h (TLC Detection). After the reaction was cooled to room temperature, the reaction solution was slowly added dropwise to 50 mL of water, and a large amount of yellow solid was formed. After standing for 30 min, filter and vacuum dry to obtain crude product. Weigh the crude product (1.26g, 2.53mmol) and dissolve it in 4mL of dichloromethane, add 2.22mL of trifluoroacetic acid (30mmol), and stir at room temperature for 3-5h (TLC detection). Then the pH of the reaction solution was adjusted to 9 with saturated sodium bicarbonate solution, extracted with dichloromethane (3×5 mL), washed with saturated sodium chloride solution, and the organic layer was dried with anhydrous sodium sulfa...
Embodiment 3
[0041] Example 3: 3,5-Dimethyl-4-((2-((1-(prop-2-yn-1-yl)piperidin-4-yl)amino)thieno[3,2-d ]Pyrimidine-4-yl)oxy)benzonitrile (9)
[0042]
[0043] Weigh Intermediate 8 (0.5mmol, 0.19g) in 5mL DMF, then add anhydrous potassium carbonate (1.0mmol, 0.14g) and bromopropyne (0.6mmol, 0.07g) in sequence, and react at room temperature (TLC detection The reaction is complete). After the reaction was completed, 20 mL of saturated brine was added to the reaction solution, washed with ethyl acetate (3 x 15 mL), the organic layer was dried with anhydrous sodium sulfate, filtered, and concentrated. Fast column chromatography separation, and then recrystallization from ethyl acetate-petroleum ether to obtain the target compound 9. 1 H NMR(400MHz, DMSO-d 6 )δ8.20(d,J=5.3Hz,1H,C 6 -thienopyrimidine-H),7.72(s,2H, C 3 ,C 5 -Ph-H), 7.27(s, 1H, C 7 -thienopyrimidine-H), 6.88(s,1H,NH), 3.69(s,1H), 3.22(s,2H, N-CH 2 ), 3.13 (s, 1H, CH ≡), 2.74 (s, 2H), 2.12 (s, 6H), 1.90-1.30 (m, 6H). 13 C NMR(100MHz...
