Brief introduction of (2-Chloropyridin-4-yl)methanol

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 100704-10-7, (2-Chloropyridin-4-yl)methanol.

Synthetic Route of 100704-10-7, 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 100704-10-7, name is (2-Chloropyridin-4-yl)methanol. This compound has unique chemical properties. The synthetic route is as follows.

Step 4b: Synthesis of 4-(bromomethyl)-2-chloropyridine (2-chloropyridin-4-yl)methanol (1.1 g, 7.3 mmol) is dissolved in 20 mL DCM; flushed with argon and cooled to 0 C. PBr, (0.76 mL; 8.1 mmol) is added drop wise via a syringe (solution turned cloudy) and reaction mixture is stirred at RT for 3 h. Cooled to 0 C and quenched with 5 mL water. The reaction mixture is ad j usted to pi f 7 by the addition of 2M K2CO3. The aqueous and organic layer are separated and the aqueous layer is extracted 3x with EtOAc. The organic layers are combined, dried over anhydrous sodium sulfate, filtered and deposited on silica. Column chromatography on silica gel (pre-washed with 1% NEt3), using a solvent gradient from hexanes to EtOAc lead to the isolation of the product as pale pink crystals (700 mg, 50% yield based on recovered starting material). NMR (300 MHz, CDCI3) delta 8.37 (d, J = 5.1 Hz, 1H), 7.35 (s, 1H), 7.27 – 7.20 (m, 1 H ), 4.35 (s, 21 1).
