Synthesized using 3-chloro-6-methylpyridazine (1.00 g, 7.78 mmol) and phenylboronic acid (1.42 g, 11.67 mmol) according to Method C. Crude product was purified by flash chromatography on silica-gel using a mixture of hexane/ethyl acetate (2:1) as eluent. White solid. Yield: 1.00 g, 76%. 1H NMR (CDCl3, 500 MHz): δH (ppm)=2.76 (s, 3H), 7.39 (d, J=8.5 Hz, 1H), 7.46-7.55 (m, 3H), 7.76 (d, J=8.5 Hz, 1H), 8.03-8.09 (m, 2H); 13C NMR (CDCl3, 125 MHz): δC (ppm)=22.0, 123.9, 126.9, 127.2, 128.9, 129.7, 134.4, 136.4, 157.2, 158.5; (ESI): m/z=170.96 [M+H]+.
