Procedure

To a solution of the compound obtained in Example 32 (940 mg) in methylene chloride (40 mL) was added 3-chloroperbenzoic acid (1.09 g) under ice-cooling and the mixture was stirred at room temperature for 3 hours. To the reaction mixture was added an aqueous sodium thiosulfate solution and the mixture was stirred and extracted with chloroform. The extract was concentrated in vacuo and the resultant crude product was purified by a column chromatography on NH-silica gel (Chromatorex NH silica gel/Fuji Silicia Chem., solvent; hexane/ethyl acetate=50/50 to 0/100) to give 6-(2-chlorophenyl)-7-(4-chlorophenyl)-3-(N-cyclopentylcarbamoyl)-2-methylsulfonyl-pyrazolo[1,5-a]pyrimidine (1.0 g; yield: 100%) as a colorless solid.
