| | 2-Chloro-6-methyl-3-pyridinecarbonitrile Usage And Synthesis |
| Uses | 2-Chloro-6-methyl-3-pyridinecarbonitrile, is a building block used for the synthesis of various biologically active compounds. It can be used for the preparation of 2-(Alkoxycarbonyl)-3-Anilinobenzo[b]thiophenes and Thieno[2,3-b]pyridines as new potent anticancer agents. | | Chemical Properties | light yellow to brown cryst. flakes or needles | | Uses | 2-Chloro-6-methyl-3-pyridinecarbonitrile, is a building block used for the synthesis of various biologically active compounds. It can be used for the preparation of 2-(Alkoxycarbonyl)-3-Anilinobenzo[b]thiophenes and Thieno[2,3-b]pyridines as new potent anticancer agents. | | Uses | 2-Chloro-6-methyl-3-pyridinecarbonitrile (2-chloro-6-methylnicotinonitrile) may be used in the preparation of methyl-2-nitropyridinecarboxamides. | | Synthesis | Step 1: 6-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (45.0 g, 335 mmol) was added to phosphorochloridic acid (652 g, 4250 mmol) and the reaction was stirred at 130°C for 2 hours. After the reaction was completed, the reaction solution was concentrated and the resulting residue was dissolved in dichloromethane and the pH was adjusted to 8 by slowly adding 4 M aqueous sodium hydroxide.The organic layer was separated, washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure to give 2-chloro-6-methylnicotinonitrile (51.0 g, 99% yield).1H NMR (400 MHz, CDCl3) δ 2.65 (s, 3H), 7.24 (d, J = 8.0 Hz, 1H), 7.89 (d, J = 8.0 Hz, 1H). | | References | [1] Patent: US2017/145005, 2017, A1.
