The downstream synthesis method of this compound is introduced below.
(2d) 2,6-Dichloro-3-methyl-5-nitropyridine [Formula 21]; Anhydrous trifluoromethanesulfonic acid (21.9 ml, 129 mmol) was dropped into a mixture of tetramethyl ammonium nitrate (17.3 g, 127 mmol) and dichloromethane (60 ml) at 0C under nitrogen flow, and the reaction mixture was stirred for 1.5 hours while elevating to room temperature. After a 10: 1.5 mixture (13.7 g) of 2,6-dichloro-3-methylpyridine and 2,4-dichloro-5- methylpyridine in dichloromethane (20 ml) was added and stirred for 30 minutes at room temperature, the reaction mixture was stirred under reflux for 48 hours. The reaction mixture was poured into a saturated sodium bicarbonate solution, and extracted with dichloromethane (200 ml), and after washed with water, dried over magnesium sulfate. The residue obtained by evaporating the solvent was triturated with heptane, thereby yielding the title compound (6.55 g, 31.6 mmol) as a pale brown solid. ¹H NMR (400MHz, DMSO-d6)8 ppm; 2.42(3H, s), 8.70(1H, s).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 58584-94-4, 2,6-Dichloro-3-methylpyridine.
