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.124236-37-9, name is Methyl 5-(trifluoromethyl)picolinate, molecular formula is C8H6F3NO2, molecular weight is 205.134, as common compound, the synthetic route is as follows.SDS of cas: 124236-37-9
Compound SM (1.0 g, 4.87 mmol) was dissolved in MeOH (15 mL). At 0 C, NaBH4 (368.9 mg, 9.75 mmol) was added portionwise with stirring. Reaction at room temperature for 1 hour. TLC showed the reaction was completed. The pH was adjusted to 5-6 with 1 M HCl solution and the EA extracted (20 mL x 3). The combined organic phases were dried over anhydrous sodium sulfate, filtered and concentrated to give the title compound (710.0 mg, 82.2%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,124236-37-9, Methyl 5-(trifluoromethyl)picolinate, and friends who are interested can also refer to it.
