Electric Literature of 261723-32-4, Adding some certain compound to certain chemical reactions, such as: 261723-32-4, name is (3-Bromo-2-fluorophenyl)methanol,molecular formula is C7H6BrFO, 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 261723-32-4.
6.4 {2-Fluoro-3-[2-(3-methoxyphenyl)imidazo[1,2-a]pyridin-6-yl]phenyl}methanol 300 mg of (3-bromo-2-fluorophenyl)methanol are dissolved in 15 ml of toluene and 5 ml of ethanol and degassed under a stream of argon for 10 min. 101 mg of tetrakis(triphenylphosphine)palladium, 580 mg of 2-(3-methoxyphenyl)imidazo[1,2-a]pyridine-6-boronic acid and 5 ml of a 2M sodium carbonate solution are subsequently added thereto. The mixture is heated at 80 C. for 16 hours and then, after cooling to ambient temperature, concentrated under reduced pressure. The residue is taken up between water and ethyl acetate and then the organic phase is separated, dried and concentrated under reduced pressure. The residue is purified by chromatography on silica gel, elution being carried out with a dichloromethane/ethyl acetate mixture. 254 mg of compound are obtained. M.p.=143-144 C. 1H NMR spectrum (d6-DMSO, delta in ppm): 3.85 (s, 3H); 4.65 (d, 2H); 5.35 (t, 1H); 6.95 (d, 1H); from 7.3 to 7.4 (m, 2H); 7.45 (d, 1H); from 7.5 to 7.65 (m, 4H); 7.7 (d, 1H); 8.5 (s, 1H); 8.75 (s, 1H). M+H=349.
