실험 절차

To a mixture of 5-bromopicolinic acid 38-3 (309 mg, 1.53 mmol), (2′-fluoro-2,4′-bipyridin-5-yl)methanamine 38-2 (312 mg, 1.53 mmol) and HATU (582 mg, 1.53 mmol) in DMF (7 mL) was added DIEA (0.76 mL, 4.59 mmol). The mixture was stirred at room temperature for 2 hours. The mixture was diluted with ethyl acetate (100 mL), washed with H2O and brine, dried over Na2SO4, and concentrated to dryness by rotary evaporation. The crude product was purified by silica gel flash chromatography, eluted with 5% methanol containing ˜7N ammonia in dichloromethane to give 5-bromo-N-((2′-fluoro-2,4′-bipyridin-5-yl)methyl)picolinamide 38-4 as yellow solid. MS m/z 387.1 (M+1)
