실험 절차

According to Scheme 22 Method B: To a mixture of 5-bromo-2-methoxypyridine (1 eq, 1.06 mmol, 0.14 mL), KOtBu (1.5 eq, 1.60 mmol, 0.18 g), Pd(OAc)2 (0.02 eq, 21 μmol, 48 mg), BINAP (0.04 eq, 42 μmol, 26 mg) in degassed DMF (1.5 mL) was added 4-fluoro-N-methylbenzenamine (1.2 eq, 1.28 mmol, 0.14 mL). The reaction mixture was microwaved at 130° C. for 5 min. The reaction mixture was quenched with water and the aqueous phase was extracted with AcOEt. The organic fraction washed brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The crude product was purified by silica gel chromatography (AIT Flashsmart prepacked column 15 g SiO2, CH2Cl2/AcOEt 90/10) to afford N-(4-fluorophenyl)-6-methoxy-N-methylpyridin-3-amine (0.08 mmol, 20 mg, 8%) as a yellow oil.
