Potassium Carbonate → HCID 59773474, compound

Participants

Reaction Steps

A solution of 4.0 eq. of quinoline-8-thiol hydrochloride (39, Aldrich, cat. no. 35,978-5) was dissolved in DMF. To this was added 32.0 eq. of potassium carbonate. The mixture was stirred at room temperature for 20 minutes and 1.0 eq of 2-bromomethyl-benzoic acid methyl ester (40, J. Org. Chem, 2002, 67, 2160) was added. The mixture was stirred at room temperature for a time sufficient enough for reaction completion. The mixture was diluted with 0.1 M citric acid and extracted with EtOAc. The organic layer was washed with brine and dried with Na2SO4, filtered, and concentrated. The product was purified by flash chromatography on silica gel using a mixture of EtOAc-hexanes as eluant to give 41.
