Category: 27652-89-7

Adding a certain compound to certain chemical reactions, such as: 27652-89-7, (4-Chlorophenyl)(pyridin-2-yl)methanol, 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, 27652-89-7, blongs to pyridine-derivatives compound. category: pyridine-derivatives

The compounds of the present invention were synthesized according to the procedure, which is illustrated schematically in FIG. 1 for three MPH alkyl analogs. Referring to FIG. 1, para-bromochlorobenzene 1 was converted into a Grignard reagent with Mg/THF which was then reacted with the pyridine-2-carboxaldehyde 2 to produce the alcohol 3. The alcohol 3 was oxidized with pyridinium chlorochromate in CH2Cl2 to produce the ketone 4. The ketone 4 was then reacted with a Grignard reagent that contains the required R group to produce the alcohol 5. After dehydration with refluxing HCl, the resulting Z and E olefin mixture 6 was hydrogenated with 10% Pt/C in HOAc containing 3% CF3COOH to produce the final compounds 7 with a ratio of about 40:60 of the R,R/S,S and R,S/S,R racemates for the ethyl compound. The racemates were separated by column chromatography and their relative configurations were determined by x-ray crystallography.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,27652-89-7, its application will become more common.

In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 27652-89-7, name is (4-Chlorophenyl)(pyridin-2-yl)methanol, the common compound, a new synthetic route is introduced below. COA of Formula: C12H10ClNO

To a stirred solution of (4-chlorophenyl) (pyridin-2-yl) methanol (5 g, 22.83 mmol) in CH2C12 (85 mL) under argon atmosphere was added pyridinium chlorochromate (5.9 g, 27.37 mmol, 1.2 equiv) and celite (5 g) at 0 C. The reaction mixture was warmed to room temperature and stirred for 2 h. After completion of the reaction, the reaction mixture was filtered through celite, washed with CH2C12 and the filtrate was concentrated under reducedpressure. Purification using silica gel column chromatography (20% EtOAc Hexanes as eluent) afforded 3.5 g of (4-chlorophenyl) (pyridin-2-yl) methanone (Yield = 7 1%). ESI + MS: m/z 218 ([M + Hj).

The synthetic route of 27652-89-7 has been constantly updated, and we look forward to future research findings.
