Related Products of 53636-70-7, 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.53636-70-7, name is 6-Methyl-2,3-pyridinedicarboxylic acid, molecular formula is C8H7NO4, molecular weight is 181.1455, as common compound, the synthetic route is as follows.
EXAMPLE 14 A mixture of 6-methylpyridine-2,3-dicarboxylic acid (19.75 g) and acetic anhydride (51 ml) was stirred and heated in an oil bath (bath temperature 110 C.) for 5 hours. The solvent was removed in vacuo and a 2:1 mixture of dichloromethane and ether was added, giving a dark brown solid. A solution of this solid in dichloromethane was passed through a pad of silica gel, eluding with dichloromethane, and the solvent was then evaporated to give partially purified 6-methylpyridine-2,3-dicarboxylic acid anhydride (12.1 g).
Statistics shows that 53636-70-7 is playing an increasingly important role. we look forward to future research findings about 6-Methyl-2,3-pyridinedicarboxylic acid.
