実験手順

Pyridinium bromide perbromide (1.00 g) was added to a solution of 7-chloro-4-(4-fluorophenyl)-2,2-dimethyl-2H-chromen (a compound obtained in Reference Example 5(3); 1.00 g) in dichloromethane (15 mL) under ice-cooling and the mixture was stirred at room temperature for 1.5 hours. The reaction mixture was poured into a 15% aqueous solution of sodium thiosulfate and extracted with ethyl acetate. The organic layer was washed successively with a saturated solution of sodium bicarbonate and brine, dried over sodium sulfate and concentrated in vacuo. The resultant residue was purified by column chromatography on silica gel (Solvent: n-hexane/chloroform=100/0 to 95/5) to give the titled compound (1.26 g) as a colorless powder.
