実験手順

A mixture of 4-bromo-2-(methoxymethyl)-5-methyl-2,3-dihydrobenzofuran-7-amine (8c) (0.85 g, 3.1 mmol), pyridin-4-ylboronic acid (0.76 g, 6.2 mmol), Cs2CO3 (2.5 g, 7.8 mmol), Pd(PPh3)4 (0.18 g, 0.16 mmol) and water (6 mL) in DMF (20 mL) was stirred at 135° C. under N2 for 1 h. It was cooled to ambient temperature, poured into water (50 mL), extracted with EtOAc (60 mL), washed with water, brine, dried and concentrated. The residue was purified by column chromatography on silica gel eluting with hexanes/EtOAc (20:1 to 5:1 to 1:1) to give the title compound (8d) as a yellow oil. MS-ESI (m/z): 271 (M+1)+.
