Versuchsvorschrift

EDC (1.3 equiv.) was added to a solution of 4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (1.0 equiv.), 2-(2-cyanopropan-2-yl)isonicotinic acid (1.2 equiv.), HOAt (1.3 equiv.) in DMF (0.19 M). The mixture was stirred at ambient temperature 3 hrs. The reaction mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed sequentially with 1M aqueous sodium hydroxide and brine, dried over sodium sulfate, filtered, and concentrated to yield 2-(2-cyanopropan-2-yl)-N-(4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)isonicotinamide in 97% yield. LCMS (m/z) (M+H)=406.2, Rt=1.10 min.
