HCID 675403767-Benzylamino-3-bromo-6-[4-(4-methylphenyl)piperidine-1-carbonyl]pyrazolo[1,5-a]pyrimidineYield 77%

Procedure

In the same manner as in Example 21, step 5 and using 7-benzylamino-3-bromopyrazolo[1,5-a]pyrimidine-6-carboxylic acid (0.20 g, 0.58 mmol) obtained in Example 22, step 3 instead of 7-benzylamino-3-ethoxycarbonylpyrazolo[1,5-a]pyrimidine-6-carboxylic acid and 4-(4-methylphenyl)piperidine hydrochloride (0.15 g, 0.69 mmol), the title compound (0.22 g, 77%) was obtained.
