Potassium Carbonate → HCID 22340987, compound

Participants

Reaction Steps

To a solution of 2-chloro-5-(3-chloro-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridin-2-yl)-4-fluorophenol (0.5 g) and 2-chloropyrimidine (0.25 g),in a mixed solvent of 2-butanone:dimethylsulfoxide (1:4) (50 ml) was added potassium carbonate (0.35 g) at room temperature. After addition, the mixture was heated at reflux for 12 hours under a nitrogen atmosphere. The mixture was allowed to cool to room temperature and partitioned between ethyl acetate and brine. The organic phase was washed with brine (×2) and dried over anhydrous sodium sulfate. The solvent was removed in vacuo and the residue was purified by column chromatography on silica gel (eluent, ethyl acetate:hexane, 2:1) to give the desired compound (0.47 g).
