Reaction Steps

The mixture of (R)-4-bromo-2,5-dimethyl-2,3-dihydrobenzofuran-7-amine (3g) (1.0 g, 4.3 mmol), pyridin-4-ylboronic acid (1.08 g, 8.77 mmol), Cs2CO3 (3.56 g, 10.9 mmol), Pd(PPh3)4 (0.506 g, 0.438 mmol) and water (9 mL) in DMF (44 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 (150 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 (3h) as a solid. MS-ESI (m/z): 241 (M+1)+.
