実験手順

Synthesized using 2-bromo-5-methyl-pyridine (2.92 g, 16.95 mmol) and phenylboronic acid (3.09 g, 25.4 mmol) according to Method C. Crude product was purified by flash chromatography on silica-gel using a mixture of hexane/ethyl acetate (8:1) as eluent. White solid. Yield: 1.99 g, 70%. 1H NMR (CDCl3, 500 MHz): δH (ppm)=2.38 (s, 3H), 7.37-7.43 (m, 1H), 7.44-7.51 (m, 2H), 7.54-7.60 (m, 1H), 7.60-7.67 (m, 1H), 7.95-8.00 (m, 2H), 8.51-8.55 (m, 1H); 13C NMR (CDCl3, 125 MHz): δC (ppm)=18.1, 120.0, 126.7, 128.6, 128.7, 131.5, 137.3, 139.4, 150.1, 154.8; (ESI): m/z=169.97 [M+H]+.
