Embodiment 1
[0188] Compound 1: tert-butyl 2-((((3-(2-cyanoethyl)pyridin-2-yl)methyl)(methyl)amino)methyl)-1H-benzimidazole-1-carboxylate ester
[0189]
[0190] Step a: 3-(2-Methylpyridin-3-yl)acrylonitrile
[0191] 3-Bromo-2-methylpyridine (1.72g, 10mmol), acrylonitrile (3.29mL, 50mmol), palladium acetate (244mg, 1mmol), tetra-n-butylammonium chloride (2.78g, 10mmol) and bicarbonate Sodium (4.2 g, 50 mmol) was dissolved in 15 mL of N,N-dimethylformamide (DMF). mixture in N 2Under the protection, it was placed in the microwave at 110°C for 5 hours. After cooling, the DMF was spin-dried, the residue was separated with water and dichloromethane (DCM), the organic phase was dried over anhydrous sodium sulfate, concentrated by filtration, and the residue was column chromatographed to obtain the title compound as a white gum (1.33 g, recovered rate of 93%).
[0192] 1 H NMR (300MHz, CDCl 3 ,ppm):δ8.52-8.50(m,1.5H),8.18(d,0.5H,J=7.8Hz),7.72(d,1H,J=7.8Hz),7.63(d,1H,J=16.5 Hz),7.37(d,0...
Embodiment 2
[0217] Compound 2: 3-(2-((((1H-benzimidazol-2-yl)methyl)(methyl)amino)methyl)pyridin-3-yl)propionitrile
[0218]
[0219] Under stirring at 0°C, 3-(2-cyanoethyl)pyridin-2-yl)methyl)(methyl)amino)methyl)-1H-benzimidazole-1-carboxylic acid tert-butyl ester ( 42 mg, 0.104 mmol) in 5 mL of dichloromethane was added trifluoroacetic acid (119 μL, 1.55 mmol), and the mixture was stirred at room temperature for 2 h. The solvent and residual trifluoroacetic acid were spin-dried, and the residue was neutralized with saturated sodium carbonate solution. After the aqueous phase was extracted three times with dichloromethane, the organic phases were combined, dried over anhydrous sodium sulfate, filtered and concentrated, and the residue was obtained by column chromatography. The compound was light yellow gum (28 mg, yield 90%).
[0220] 1 H NMR (300MHz, CDCl 3 )δ10.15(brs,1H),8.57(d,1H,J=4.5Hz),7.65-7.62(m,3H),7.32-7.23(m,3H),3.88(s,2H),3.80(s ,2H),3.06(t,2H,J=6.9Hz),2.77(t,2H,J=6....
Embodiment 3
[0222] Compound 3: 3-(2-(((isoquinolin-1-ylmethyl)(methyl)amino)methyl)pyridin-3-yl)propionitrile
[0223]
[0224]Under stirring, 1,2 - Acetic acid (10.6 μL, 0.183 mmol) and sodium triacetoxyborohydride (116 mg, 0.549 mmol) were successively added to 2 mL of dichloroethane solution, and the mixture was stirred at room temperature for 24 h. The solvent was evaporated to dryness, and the residue was subjected to column chromatography to obtain the title compound as a yellow oil (36 mg, yield 63%).
[0225] 1 H NMR (300MHz, CDCl 3 )δ8.94-8.91(m,2H),8.52(d,1H,J=8.1Hz),8.28(d,1H,J=7.8Hz),8.15-7.95(m,4H),7.67-7.63(m ,1H),4.72(s,2H),4.36(s,2H),3.19-3.17(m,2H),2.82-2.80(m,5H); 13 C NMR (100MHz, CDCl 3 , ppm): δ157.2, 156.0, 147.4, 141.4, 137.5, 136.2, 133.4, 130.1, 127.2, 125.4, 122.9, 120.7, 118.9, 62.1, 61.8, 43.1, 27.2, 18.0; EI-MS: 316 (M + );HRMS(EI): Calculated value: C 20 h 20 N 4 (M) + :316.1688; Measured value: 316.1685.
