Dimethylformamide → HCID 21195140, compound

Participants

Reaction Steps

A solution of 6-bromo-4'-(4-methoxyphenyl)-2,2':6',2"-terpyridine (15.1 mmol) in 100 mL of dry THF is added dropwise to a solution of n-butyl lithium (15.5 mmol) in 20 mL of tetrahydrofuran (THF) at -78° C. under H2 over 12 minutes. After 10 minutes the reaction mixture is treated with dimethylformamide (7.5 mL) in THF (15 mL), and quenched after 15 minutes with aqueous 10% HCl. The product is extracted into cold chloroform which is washed with saturated sodium chloride solution, filtered, and the solvent is evaporated. The residue is triturated with CH3CN, filtered, and recrystallized from ethyl acetate to provide the desired compound.
