Electric Literature of 77199-09-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 77199-09-8, name is Ethyl 5-bromopicolinate, molecular formula is C8H8BrNO2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: Ester (FAE, 4a-m, 2a or 2b) (500 mg scale, 1 equiv.) was dissolvedin 6 ml THF at 0 C in a 25 ml round-bottom flask. ThenNaOH(aq) (5 equiv.) was added dropwise and stirred for 15 h atroom temperature. After starting materials were consumed (byTLC), water (20 ml) was added. The reaction mixture was washedwith ethyl acetate (2 x 20 ml). The aqueous solution was acidified(pH 2-3) with 1 M HCl(aq) causing precipitation of a solid, whichwas filtered and dried under vacuum. Recrystallization in ethanolafford clean compound.
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 77199-09-8, Ethyl 5-bromopicolinate.
