实验步骤: Into a 50-mL round-bottom flask, was placed a solution of 4-(dimethylamino)cyclohexan-1-ol (127 mg, 0.89 mmol, 1.50 equiv) in N,N-dimethylformamide (15 mL). This was followed by the addition of sodium hydride (71 mg, 1.77 mmol, 3.00 equiv, 60%). The resulting solution was stirred for 30 minutes at 80° C. in an oil bath. 4-chlorothieno[2,3-b]pyridine (100 mg, 0.59 mmol, 1.00 equiv) was added to the mixture. The resulting solution was stirred for 3 h at 120° C. in an oil bath. The reaction was then quenched by the addition of 10 mL of ethanol. The resulting mixture was concentrated under vacuum. The residue was purified on a silica gel column with dichloromethane/methanol (10:1). The resulting product (50 mg) was further purified by Prep-HPLC with the following conditions: Column, SunFire Prep C18, 19*150 mm 5 um; mobile phase, CH3CN and water with 0.05% NH4HCO3 (3.0% water with 0.05% NH4HCO3 up to 3.0% in 1 min, up to 4.7.0% in 13 min, up to 100.0% in 2 min); Detector, uv 254/220 nm. This resulted in 9.6 mg (6%) of N,N-dimethyl-4-[thieno[2,3-b]pyridin-4-yloxy]cyclohexan-1-amine as a white solid.
