With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.3678-62-4, name is 2-Chloro-4-methylpyridine, molecular formula is C6H6ClN, molecular weight is 127.57, as common compound, the synthetic route is as follows.Recommanded Product: 3678-62-4
Step 1 2-Methoxy-4-methylpyridine Procedure: A mixture of 2-chloro-4-methylpyridine (20 g, 0.156 mol) and NaOCH3 (9.3 g, 0.172 mol) in DMSO (200 mL) was stirred at 100 C. for 4 hours. The solution was added to H2O and then extracted with ethyl acetate (50 mL*2). The organic layer was washed with H2O (300 mL) brine (300 mL) and dried concentrated to give 2-methoxy-4-methylpyridine (9 g, 46%). LC-MS: 124 [M+H]+, tR=1.21 min.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,3678-62-4, 2-Chloro-4-methylpyridine, and friends who are interested can also refer to it.
