Procedure:
169 a) To a suspension of N-(3-bromo-phenyl)-methanesulfonamide (1.0 g, 4.0 mmol) and potassium carbonate (0.61 g, 4.4 mmol) in acetone (10 mL) was added iodomethane (0.30 mL, 4.8 mmol). The mixture was stirred at room temperature for 18 hours, diluted with dichloromethane (30 mL), filtered through a plug of diatomaceous earth and evaporated under reduced pressure. N-(3-Bromo-phenyl)-N-methyl-methanesulfonamide was isolated a tan viscous oil (1.08 g, 100%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.53 (s, 1H), 7.43 (d, J=7.9 Hz, 1H), 7.35 (d, J=8.2 Hz, 1H), 7.29-7.23 (m, 1H), 3.32 (s, 3H), 2.86 (s, 3H). MS=286, 288 (MH)+. 169 b) A suspension of N-(3-bromo-phenyl)-N-methyl-methanesulfonamide (1.0 g, 3.8 mmol) and copper cyanide (0.78 g, 8.7 mmol) in N,N-dimethylformamide (5 mL) was heated at 150° C. for 18 hours. The mixture was cooled to room temperature. A solution of potassium cyanide (5 g) and water (50 mL) was added to the vigorously stirred dark mixture and was stirred for 1 hour. The mixture was extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with water (2×30 mL) then saturated aqueous sodium chloride (30 mL), dried over magnesium sulfate and filtered. The filtrate was evaporated to a yellow oil (1.0 g). The residue was purified via flash chromatography (silica gel column and 5%→50% ethyl acetate:hexane). N-(3-Cyano-phenyl)-N-methyl-methanesulfonamide was isolated as a tan solid (0.184 g, 23%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.69-7.64 (m, 2H), 7.58 (d, J=7.7 Hz, 1H), 7.54-7.49 (m, 1H), 3.36 (s, 3H), 2.88 (s, 3H). MS=211 (MH)+. 169 c) -(3-Aminomethyl-phenyl)-N-methyl-methanesulfonamide was prepared from N-(3-Cyano-phenyl)-N-methyl-methanesulfonamide (0.184 g, 0.875 mmol) in a manner analogous to Example 156b. Product isolated as a tan viscous oil (0.184 g, 98%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.39-7.33 (m, 2H), 7.28-7.23 (m, 2H), 3.90 (s, 2H), 3.33 (s, 3H), 2.86 (s, 3H). MS=215 (MH)+. 169 d) N-{3-[(2-Chloro-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino)-methyl]-phenyl}-N-methyl-methanesulfonamide was prepared from 8-bromo-2-chloro-[1,2,4]triazolo[1,5-a]pyridine (184.0 mg, 0.7915 mmol) and N-(3-aminomethyl-phenyl)-N-methyl-methanesulfonamide (188.0 mg, 0.8773 mmol) in a manner analogous to Example 2d. Product isolated as a yellow resin (0.082 g, 28%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.89 (d, J=6.7 Hz, 1H), 7.42-7.36 (m, 2H), 7.33-7.29 (m, 2H), 6.85 (t, J=7.4 Hz, 1H), 6.39 (d, J=7.8 Hz, 1H), 5.43-5.38 (m, 1H), 4.49 (d, J=5.7 Hz, 2H), 3.32 (s, 3H), 2.83 (s, 3H). MS=366, 368 (MH)+. 169 e) N-Methyl-N-[3-({2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino}-methyl)-phenyl]-methanesulfonamide was prepared from N-{3-[(2-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino)-methyl]-phenyl}-N-methyl-methanesulfonamide (82.0 mg, 0.224 mmol) and 4-(4-methyl-piperazin-1-yl)-phenylamine (48.0 mg, 0.251 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (25.0 mg, 0.0457 mmol) as the ligand in a manner analogous to Example 2d. Product isolated as a tan foam (0.024 g, 21%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.82 (d, J=6.6 Hz, 1H), 7.47 (d, J=8.8 Hz, 2H), 7.42-7.28 (m, 4H), 6.96 (d, J=8.8 Hz, 2H), 6.65 (t, J=7.2 Hz, 1H), 6.54 (s, 1H), 6.29 (d, J=7.6 Hz, 1H), 5.19 (t, J=5.6 Hz, 1H), 4.49 (d, J=5.6 Hz, 2H), 3.30 (s, 3H), 3.17-3.13 (m, 4H), 2.81 (s, 3H), 2.62-2.57 (m, 4H), 2.36 (s, 3H).
