실험 절차
A suspension of 3-(2-chlorophenyl)-6-(2,4-difluorophenoxy)-1H-pyrazolo[3,4-b]pyrazine (2.70 g, 7.5 mmol) in 500 mL carbon tetrachloride was bubbled with chlorine gas for 16 hours at room temperature while stirring. The reaction mixture was concentrated under reduced pressure, and the residue was purified by chromatography (methylene chloride/hexanes 2:3 to 1:0) to give 1.21 g of 5-Chloro-3-(2-chloro-phenyl)-6-(2,4-difluoro-phenoxy)-1H-pyrazolo[3,4-b]pyrazine. Mass spec. M+1=394.
