Procedure

To a solution of the compound obtained in Example A1 (106 mg) in toluene (4 mL) and dimethylformamide (1.5 mL) were added sodium azide (86 mg) and triethylamine hydrochloride (183 mg), and the mixture was stirred at 120° C. for 24 hours. To the reaction mixture were further added sodium azide (90 mg) and triethylamine hydrochloride (183 mg), and the mixture was stirred for 21 hours. After cooling to room temperature, the reaction mixture was filtered through Celite to remove precipitates, and the filtrate was concentrated in vacuo. The resultant crude product was purified successively by column chromatography on silica gel (solvent; chloroform/methanol=100/0 to 95/5) and gel-permeation chromatography (solvent; chloroform) to give 6-(2-chlorophenyl)-7-(4-chlorophenyl)-3-[N-[1-(1,2,3,4-tetrazol-5-yl)cyclohexyl]carbamoyl]-pyrazolo[1,5-a]pyrimidine (95 mg, yield: 83%) as a powder.
