实验步骤: A mixture of 3-chloro-5-fluoro-benzonitrile (1 g, 6.45 mmol), 1-methyl-piperazine (0.715 ml, 6.45 mmol), and K2CO3 (2.64 g, 19.3 mmol) in DMF (5 ml) was heated to 140° C. for 40 min in a microwave apparatus. The resulting slurry was filtered and the solvent was removed in vacuo to give 1 g of 3-chloro-5-(4-methyl-piperazin-1-yl)-benzonitrile. The crude reaction mixture was used in the next step without any further purification. The resulting slurry was filtered the solvent was removed in vacuo

实验步骤: A stirred suspension of 5-chloro-1-(4-methoxybenzyl)-1H-1,2,3-benzotriazol-4-ol (0.050 g, 0.173 mmol), 3-fluoro-5-chloro-benzonitrile (0.081 g, 0.518 mmol) and cesium carbonate (0.068 g, 0.207 mmol) in NMP (1.5 mL) was heated at 140° C. for 72 hours. The reaction mixture was then quenched with aqueous ammonium chloride (25 mL) and extracted with dichloromethane (2×100 mL). The combined extracts were concentrated under reduced pressure. The resulting residue was subjected to reverse phase chromatography (5-95% MeCN/H2O, 0.1% TFA). The product fractions were combined and extracted with dichloromethane (2×100 mL). The combined extracts were dried over MgSO4, filtered and concentrated under reduced pressure to yield the title product. 1H NMR (DMSO d6) δ 7.90-7.88 (m, 1H), 7.80 (s, 1H), 7.79-7.75 (m, 1H), 7.60-7.55 (m, 2H), 7.40-7.35 (d, J=6.9 Hz, 2H), 6.95-6.88 (m, 2H), 5.80 (s, 2H), 3.71 (s, 3H). The reaction mixture was then quenched with aqueous ammonium chloride (25 mL) extracted with dichloromethane (2×100 mL) The combined extracts were concentrated under reduced pressure extracted with dichloromethane (2×100 mL) The combined extracts were dried over MgSO4 filtered concentrated under reduced pressure

实验步骤: A mixture of 1-bromo-3-chloro-5-fluorobenzene (25.0 g, 120 mmol), zinc cyanide (8.45 g, 72 mmol) zinc (dust, 235 mg, 3.6 mmol), [1,1′Bis(diphenylphosphino)ferrocene] dichloropalladium(II), complex with dichloromethane (1:1) (1.5 g, 1.8 mmol) in N,N-dimethylformamide (70 ml) was heated at reflux for 1 hour. After cooling the reaction was diluted with ethyl acetate and extracted with water and brine. Silica gel chromatography afforded 15.9g (85%) 3-chloro-5-fluorobenzonitrile. was heated at reflux for 1 hour After cooling the reaction extracted with water and brine

实验步骤: Sodium tert-butoxide (92 mg, 0.96 mmol) was added to a solution of 3-chloro-5-fluorobenzonitrile (67.9 mg, 0.359 mmol) and N-(4-{(1R)-1-[(R)-(4-chlorophenyl)(hydroxy)methyl]-4,4,4-trifluorobutyl}benzoyl)-β-alanine (prepared using the procedures from INTERMEDIATE 1 and the saponification step of EXAMPLE 1, 100 mg, 0.239 mmol) in DMF (3 mL), then the resulting brown mixture was stirred at 80° C. for 16 hours. The mixture was diluted with EtOAc, then washed with 2 N HCl(aq), then washed twice with water. The organic layer was then concentrated, and the resulting yellow residue was purified by reverse phase HPLC eluting with 30-100% MeCN/water+0.1% TFA. Following lyophilization, this afforded the title compound. LC3 3.35 min.
