This compound has unique chemical properties. The synthetic route is as follows. Recommanded Product: 4,6-Dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile
2-Chloro-4, 6-dimethylnicotinonitrile4,6-Dimethyl-2-oxo-l,2-dihydropyridine-3-carbonitrile (5g, 34mmol) was added to phosphorus oxychloride (20ml). The reaction was stirred at reflux for 2 h, after which it was seen complete. Volatiles were removed and the residue triturated with petrol.The resultant solid was filtered off and washed with hexane,and dried to give a pure white solid (5.1g, 90%). deltaH (250 MHz, CDCl3) 2.55 (3 H, s, CH3), 2.57 (3 H, s, CH3),7.09 (1 H, s, ArH); deltac ( 250 MHz, CDCl3) 162.64 (C), 154.39 (C), 152.26 (C), 123.22 (CH), 114.28 (C), 108.31 (C), 24.5 (CH3), 20.54 (CH3).; m/z 189 (M + Na)
