Adding a certain compound to certain chemical reactions, such as: 18368-59-7, 3-Bromo-4-methylpyridin-2-ol, 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, 18368-59-7, blongs to pyridine-derivatives compound. Formula: C6H6BrNO

Synthesis of interaiediate V-c : 3 -Bromo-2-methoxy-4-methyl -pyridineA solution of 3-bromo-4-methyl-2-pyridone V-b (2.20 g, 11.7 mmol), in DCM (80 mL) was treated with Mel (7.29 mL, 117 mmol) and Ag2C03 (6.47 g, 23.5 mmol). The flask was stoppered and stirred under argon for 6 days. The mixture was filtered and purified by column chromatography (Si02; 10% EtOAc in cyclohexane) to afford the desired product V-c as a clear mobile oil (1.83 g, 80%). 1H NMR (300 MHz, CDC13) delta 7.94 (d, J = 5.0 Hz, 1H), 6.77 (d, J= 5.1 Hz, 1H), 4.00 (s, 3H), 2.39 (s, 3H).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,18368-59-7, its application will become more common.

Electric Literature of 18368-59-7, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 18368-59-7, name is 3-Bromo-4-methylpyridin-2-ol. This compound has unique chemical properties. The synthetic route is as follows.

Example 195; Synthesis of 3-iodo-4-methyl-1-(3-(trifluoromethoxy)phenyl)pyridin-2? HP-one; A resealable pressure vessel was charged with copper(l) iodide (0.081 g, 0.425 mmol), 1-iodo-3-(trifluoromethoxy)benzene (0.434 ml, 2.77 mmol) and 3-bromo-4- methylpyridin-2(1H)-one (0.400 g, 2.13 mmol). To the mixture was added dioxane (3 ml.) followed by N1,N2-dimethylethane-1,2-diamine (0.092 ml, 0.851 mmol). The vessel was purged with Argon, sealed, and heated to 1100C for 24 hrs. The mixture was cooled to RT, diluted with EtOAc and washed with water and brine. The organic fraction was adsorbed onto silica gel and purified by silica gel chromatography using 15-80% Hexanes:EtOAc to afford 3-iodo-4-methyl-1- (3-(trifluoromethoxy)phenyl)pyridin-2(1 H)-one as an off-white solid. M+H+ = 396.0.

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 18368-59-7, 3-Bromo-4-methylpyridin-2-ol.
