Procedure

A mixture of 5.50 g (19 mmol) of Na2CO3×10H2O, 100 ml of water and 30 ml of methanol was purged with argon for 30 min. The obtained solution was added to a mixture of 2.60 g (7.7 mmol) of 2-methyl-N-[3-methyl-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl]aniline, 2.68 g (7.7 mmol) of N-[(6-bromopyridin-2-yl)methyl]-2,6-diisopropylaniline, and 0.44 g (0.39 mmol) of Pd(PPh3)4 in 120 ml of toluene. This mixture was stirred for 12 h at 70° C., then cooled to room temperature. The organic layer was separated, the aqueous layer was extracted with 3×50 ml of ethyl acetate. The combined organic extract was washed with brine, dried over Na2SO4, and evaporated to dryness. The residue was purified by flash chromatography on silica gel 60 (40-63 um; eluent: hexane-triethylamine=20:1, vol.). Yield 2.10 g (57%) of white crystalline solid.
