反応手順

To a stirred suspension of NaH (2.6 g, 108.5 mmol) in DMF (300 mL) at 0° C., under N2, a solution of 4-pyrrolidin-1-ylmethylphenol (16 g, 90.4 mmol) was added slowly. After stirring at 0° C. for 30 min, 2,6-dibromopyridine (23.6 g, 99.4 mmol) was added and the resulting mixture was heated at 95° C. for 20 h. After cooling to RT, 200 mL of H2O was added and the mixture was extracted with EtOAc (3×300 mL). The combined organic layer was washed with brine (3×400 mL), dried over MgSO4, filtered and concentrated under reduced pressure to yield the title compound as an amber solid. This was used crude in the next step. MS m/z: 333 (M+1). Calc'd for C16H17BrN2O-333.2
