Electric Literature of 78686-79-0, Adding some certain compound to certain chemical reactions, such as: 78686-79-0, name is Methyl 5-bromo-2-chloronicotinate,molecular formula is C7H5BrClNO2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 78686-79-0.
INTERMEDIATE 31Methyl 2-chloro-5-methylnicotinate; To a solution of methyl 5-bromo-2-chloronicotinate (1.05g, 4.19mmol), K3PO4 (2.95g, 13.90mmol), methylboronic acid (0.32g, 5.26mmol) and tricyclohexylphosphine (0.11g, 0.39mmol) in toluene/water (16ml/0.8ml) under nitrogen atmosphere was added Pd(OAc)2 (0.04g, 0.18mmol). The mixture was heated at 1000C overnight under nitrogen atmosphere. The reaction mixture was then cooled to room temperature and concentrated in vacuum. Ethyl acetate was added to the residue and this organic layer was washed with water, brine, dried over MgSO4, filtered and the solvent evaporated under vacuum to yield the desired product as a yellow oil. Yield=87% LRMS: m/z 186 (M+1 )+ Retention time: 4.84min
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 78686-79-0, Methyl 5-bromo-2-chloronicotinate, other downstream synthetic routes, hurry up and to see.
