Adding some certain compound to certain chemical reactions, such as: 626-18-6, name is 1,3-Benzenedimethanol, 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 626-18-6. 626-18-6
To a stirred solution of 1, 3-phenylenedimethanol (1) (5 g, 36.496 mmol) in THF (100 mL) was treated with NaH (1.17 g, 29.197 mmol) at 0C to RT for 30 min. Ethyl iodide (2.3 ml, 29.197 mmol) in THF (10 mL) was added to above reaction mixture at OC and stirred at 60 C for 6h under nitrogen atmosphere. The reaction mixture was quenched with ice water and extracted with ethyl acetate (3x100mL). Combined organic layers were washed with brine (2×100 mL) and dried over Na2SO4, evaporated under reduced pressure. Crude residue was purified by Combi-flash chromatography using 20 % ethyl acetate in pet- ether to afford (3-(ethoxy methyl) phenyl) methanol 3 (2.1g, 12.65 mmol, 34 % yield) as a yellowish oily liquid. TLC system: 40 % ethyl acetate in pet-ether – Rf: 0.50; LCMS: m/z = 120.99 (M-46) +
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 626-18-6.
